A strong frame-mounted receiver hitch gives a travel trailer a compatible receiver for accessories or, when its rating and installation allow, light towing. For many owners, CURT 13703 Adjustable RV Trailer Hitch is a leading choice because it fits compatible frames up to 72 inches wide and lists a 3,500-pound gross trailer weight and 350-pound tongue weight rating. The products here vary substantially: some are adjustable across wide frames, one is specified for frames up to 51 inches, and others provide fewer fit or capacity details.
Match the hitch to your trailer frame and intended load before choosing. A 2-inch receiver alone does not establish towing suitability, and the lowest-rated component and the trailer or vehicle manufacturer’s limits still govern use.
CURT 13703 Adjustable RV Trailer Hitch is the best overall choice in this group for buyers seeking an adjustable frame-mounted receiver for a travel trailer. It adds a standard 2-inch receiver, fits compatible RV, camper, and motorhome frames up to 72 inches wide, and is rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight. Those ratings are limited by the lowest-rated towing component, the RV frame capacity, and manufacturer limits.
Check fitment and intended use before installation.

Detailed Reviews: Best Frame Mounted Receiver Hitch For Travel Trailer

#1 · Best Overall
1. CURT 13703 Hitch
- Material: Carbon Steel
- Material Type: Carbon Steel
- Compatible with Vehicle Type: ATV, Marine-Personal-Craft, Trailer
Best for: Wide-Frame RV Accessory Hitch.
Why it ranks #1: Its adjustable design fits compatible frames up to 72 inches wide and lists 3,500 pounds gross trailer weight and 350 pounds tongue weight.
A frame-width fit up to 72 inches and a standard 2-inch receiver make the CURT 13703 a flexible hitch for compatible RVs, campers, and motorhomes. It supports bike-free cargo carrying, accessory towing, or small-vehicle towing, with stated limits of 3,500 pounds gross trailer weight and 350 pounds tongue weight.
The adjustable mount accommodates frames up to 72 inches wide, while the 2-inch receiver accepts cargo carriers and other towing accessories, giving owners several ways to add utility at the rear of a camper or motorhome. Its 3,500-pound gross trailer weight and 350-pound tongue weight ratings set clear boundaries; actual use is limited by the lowest-rated towing component, RV frame capacity, and vehicle-maker limits. At 98.5 pounds, the hitch is also a substantial component to handle during installation.
- Fits camper and motorhome frames up to 72 inches wide
- Standard 2-inch receiver
- Rated for 3,500 pounds gross trailer weight
- Rated for 350 pounds tongue weight
- Its listed weight is 98.5 pounds, which can make handling during installation more demanding.
Skip it if you need a lighter hitch to handle during installation; Stromberg Carlson CC-300 is listed at 46.9 pounds and serves accessory-mounting needs.
Choose this for a compatible wide-frame RV when the 2-inch receiver and stated towing ratings match the planned load. Account for the 98.5-pound hitch weight and all lower component and frame limits.

#2 · Highest Capacity
2. CURT 13701 Hitch
- Material: Carbon Steel
- Material Type: Carbon Steel
- Compatible with Vehicle Type: ATV, Marine-Personal-Craft, Trailer
Best for: Higher-Rated Narrow-Frame Hitch.
Why it ranks #2: It lists 5,000 pounds gross trailer weight and 500 pounds tongue weight, with a 2-inch receiver; its fit is limited to frames up to 51 inches.
A 5,000-pound gross trailer weight rating distinguishes the CURT 13701 among these adjustable RV hitches, while its 2-inch receiver equips a camper for towing accessories. The hitch fits frames up to 51 inches wide and includes a 2-inch drop, so frame width and receiver position matter when selecting it.
The 2-inch receiver supports compatible towing accessories, and the 2-inch drop helps establish the listed receiver position for a camper installation. Its ratings are 5,000 pounds gross trailer weight, 500 pounds tongue weight, 6,000 pounds weight-distribution capacity, and 600 pounds weight-distribution tongue weight, all limited by the lowest-rated component. The frame fit reaches 51 inches wide. It is not compatible with vertical-hanging bike racks, which narrows accessory choices for some owners.
- Rated for 5,000 pounds gross trailer weight
- Rated for 500 pounds tongue weight
- 2-inch receiver with a 2-inch drop
- Fits frames up to 51 inches wide
- Not compatible with vertical-hanging bike racks.
Skip it if you use a vertical-hanging bike rack; ALMULOO AI-2445 accepts bike racks but excludes that rack style too, so choose a nonvertical carrier.
This suits owners of narrower-frame campers who need the stated higher trailer-weight rating and a 2-inch drop. Keep all component limits in view and choose a nonvertical bike carrier.

#3 · Bolt-or-Weld Mount
3. Stromberg Carlson CC-300
- Material: Alloy Steel
- Material Type: Alloy Steel
- Compatible with Vehicle Type: Car, Trailer
Best for: Adjustable Trailer Accessory Mount.
Why it ranks #3: Designed to create a 2-inch receiver on travel trailers and fifth wheels, it can be bolted on as Class I or welded on as Class II.
A 2-inch receiver for travel trailers and fifth wheels gives the Stromberg Carlson CC-300 a direct way to carry a bike rack or cargo carrier at the back of an RV. Its adjustable accessory-hitch format also offers two frame-attachment approaches, so the installation plan can account for bolting or welding.
Choose a bolted Class I installation or a welded Class II installation according to the frame-mounting approach, then use the 2-inch receiver for compatible accessories such as bike racks and cargo carriers. That makes this a practical option for adding rear carrying capacity to a travel trailer or fifth wheel without describing it as a primary towing hitch. The supplied specifications identify alloy steel construction, but do not provide a load rating or frame-width range.
- Adds a 2-inch receiver to travel trailers and fifth wheels
- Can be bolted on as Class I
- Can be welded on as Class II
- Intended for bike racks and cargo carriers
- The supplied details do not state a load rating or frame-width range.
Skip it if you need a stated load rating or frame-width limit before choosing a hitch; CURT 13703 lists both capacity figures and a frame-width maximum.
For RV owners adding a bike rack or cargo carrier to a travel trailer or fifth wheel, the CC-300 offers useful mounting flexibility. Check the frame attachment approach and load requirements before selecting it.

#4 · 72-Inch Frame Fit
4. HECASA MO-5981 Hitch
- Material: Alloy Steel
- Material Type: Alloy Steel
- Compatible with Vehicle Type: RV
Best for: 72-Inch-Frame Accessory Hitch.
Why it ranks #4: This adjustable 2-inch receiver fits frames up to 72 inches and lists 3,500 pounds gross trailer weight and 350 pounds tongue weight.
A fit for frames up to 72 inches and a 2-inch receiver give the HECASA MO-5981 broad utility for RV owners adding rear accessories. Its stated 3,500-pound gross trailer weight and 350-pound tongue weight ratings set a defined capacity, while the powder-coated finish covers the steel hitch surface.
The hitch is listed for frames up to 72 inches, with rear attachment and a 2-inch receiver that accepts a ball mount, cargo carrier, bicycle frame, trailer hitch, or winch. Those options make it adaptable for different RV accessory needs, while the 3,500-pound gross trailer weight and 350-pound tongue weight figures set boundaries for towing loads. The product is described as a direct replacement for 13703; confirm that the stated frame width and load limits suit the installation and use.
- Fits frames up to 72 inches wide
- 2-inch receiver for multiple accessory types
- Rated for 3,500 pounds gross trailer weight
- Powder-coated steel construction
- The listed ratings are limited to 3,500 pounds gross trailer weight and 350 pounds tongue weight.
Skip it if you need a higher stated trailer-weight rating; CURT 13701 lists 5,000 pounds gross trailer weight, subject to its lowest-rated component limit.
This fits RV owners seeking a 72-inch-frame receiver for varied accessories within its stated ratings. Check frame width and keep the trailer and tongue loads within the listed limits.

5. ALMULOO AI-2445 Hitch
- Material: Alloy Steel
- Material Type: Alloy Steel
- Compatible with Vehicle Type: RV
Best for: Adjustable RV Light-Towing Hitch.
Why it ranks #5: Its 2-inch receiver and direct bolt-on design suit RV accessories, while the listed 3,500-pound trailer and 350-pound tongue ratings provide capacity detail.
A three-piece adjustable design that fits frames up to 72 inches gives the ALMULOO hitch useful flexibility when adding a receiver to an RV. Its 2-inch opening supports ball mounts, cargo racks, and bike racks, while the stated 3,500-pound trailer and 350-pound tongue ratings define its towing limits.
The three-piece design adjusts for frames up to 72 inches, helping accommodate different RV frame widths, and the direct bolt-on installation keeps the attachment method straightforward. Its 2-inch receiver accepts ball mounts, cargo racks, and bike racks, making it useful for towing or carrying accessories within the stated 3,500-pound trailer and 350-pound tongue limits. The product specifically excludes vertical hanging bike racks, so choose a rack that carries bikes in another orientation.
- Three-piece adjustable design fits frames up to 72 inches
- Direct bolt-on installation
- 2-inch receiver accepts ball mounts, cargo racks, and bike racks
- Rated for 3,500 pounds trailer weight and 350 pounds tongue weight
- Does not support vertical hanging bike racks.
Skip it if you use a vertical hanging bike rack; CURT 13703 is listed for cargo carriers and towing accessories without this stated rack restriction.
This suits RV owners seeking an adjustable bolt-on receiver for accessory carrying or towing within its stated ratings. Measure the frame width and avoid it if your bike rack requires vertical hanging.

6. Buyers Products 1801125
- Material: Carbon Steel
- Material Type: Carbon Steel
- Compatible with Vehicle Type: Trailer, Truck
Best for: Wide-Mount Cargo Carrier Setup.
Why it ranks #6: The adjustable crossbar spans a 47.5-to-77-inch mounting range and the 2-inch receiver supports accessories; its listing also says not for towing.
An adjustable crossbar spanning 47.5 to 77 inches lets the Buyers Products 1801125 fit a broad range of trailer and RV mounting widths. Its 2-inch receiver adds a place for a bike rack or cargo carrier, while the product title describes light towing up to 3,000 pounds.
The 47.5-to-77-inch mounting range can help owners fit the crossbar to different trailer or RV widths, and the 2-inch receiver supports adding a bike rack or cargo carrier for extra carrying space. The title states light towing up to 3,000 pounds, but the included-components listing identifies the receiver as “Not For Towing.” Because those details conflict, buyers should resolve the intended use before treating it as a towing solution.
- Adjustable 47.5-to-77-inch mounting range
- 2-inch receiver
- Supports a bike rack or cargo carrier
- Title states light towing up to 3,000 pounds
- The included-components listing says “Not For Towing,” despite the title’s light-towing claim.
Skip it if you need an unambiguous towing receiver; CURT 13703 lists explicit trailer and tongue-weight ratings for towing accessories.
This is a candidate for RV or trailer owners prioritizing a wide adjustable mounting range and a 2-inch accessory receiver. Resolve the towing-use conflict in the listing before relying on it for towing.

7. KUAFU GO-1241 Hitch
- Compatible with Vehicle Type: Marine-Personal-Craft, Trailer
Best for: Frame-Mounted Trailer Accessory Hitch.
Why it ranks #7: It is specified for travel trailers and fifth wheels with a 2-inch receiver, but its capacity information is unclear and varies by mounting class.
The KUAFU receiver offers a 2-inch hitch for travel trailers and fifth wheels, with bolted Class I or welded Class II frame attachment options. That flexibility supports accessory use such as carrying bikes, while the listed tongue-weight limits distinguish the bolted and welded mounting approaches.
For a Class I setup, the hitch bolts to the frame and lists a maximum tongue weight of 200 pounds; the Class II approach is welded and lists 300–350 pounds of tongue weight. The 2-inch receiver is described for travel trailers and fifth wheels and can serve boats, popup campers, trailers, and bikes. A powder-coat finish is listed, and the product description also mentions towing a vehicle when trouble arises, so keep the stated mounting-specific limits in view.
- 2-inch hitch for travel trailers and fifth wheels
- Bolted Class I frame attachment option
- Welded Class II frame attachment option
- Powder-coat finish
- The listed tongue-weight limit varies by attachment method, from 200 pounds bolted to 300–350 pounds welded.
Skip it if you need a clearly stated gross trailer-weight rating; CURT 13703 specifies trailer and tongue-weight limits for its hitch.
Consider this for a trailer owner choosing between bolted and welded frame attachment for accessory or towing needs. Match the installation method to its stated tongue-weight limit and intended use.

8. HECASA NN1159 Hitch
- Material: Alloy Steel
- Material Type: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Basic Steel Receiver Addition.
Why it ranks #8: Its title identifies an adjustable 2-inch receiver for RVs and travel trailers, but the supplied data gives no frame range or capacity rating.
A 2-inch receiver and adjustable format are the defining details of the HECASA NN1159, giving RV and travel-trailer owners a way to add a receiver at the rear. Its alloy-steel construction identifies the material, but the supplied specifications do not state a frame-width fit or load rating.
The title identifies this as an adjustable trailer hitch with a 2-inch receiver for universal RV and fifth-wheel use, so buyers can consider it for adding a standard-size hitch opening to a compatible setup. Alloy steel is the listed material. However, the supplied product information gives no capacity figures, frame-width range, or installation method, leaving important compatibility and load decisions unresolved. Those gaps make it harder to assess whether the hitch matches a particular trailer or accessory load.
- 2-inch receiver stated in the product title
- Adjustable hitch format stated in the title
- Listed for RV and fifth-wheel use
- Alloy steel construction
- The supplied details state no load rating, frame-width range, or installation method.
Skip it if you need a stated capacity and frame-width limit; CURT 13703 provides both figures for comparing a compatible RV hitch.
This may suit a buyer seeking a basic adjustable 2-inch receiver for an RV or fifth wheel. Before choosing it, obtain the missing load and frame-fit details needed to evaluate the intended setup.

View on AmazonAvoid confusing receiver fit with towing capacity
A receiver that fits the frame does not automatically make the trailer safe for every towing task. The CURT 13703 listing says its 3,500-pound gross trailer weight and 350-pound tongue weight ratings are limited by the lowest-rated towing component, RV frame capacity, and vehicle-manufacturer limits. The Buyers Products 1801125 listing illustrates another important distinction: it describes a 2-inch receiver and up to 3,000 pounds of light towing, but its included-components specification says “Trailer Accessory Receiver – Not For Towing.” Treat that conflict as a reason to verify the manufacturer’s instructions and intended use rather than relying on a receiver size or a single capacity figure.
Accessories also impose loads on the hitch and frame. Confirm that the trailer frame, hitch, accessory, and installation are all suitable for the specific load before using the receiver.
Check accessory limits and frame dimensions before ordering
A 2-inch receiver does not guarantee compatibility with every rack or mounting position. ALMULOO explicitly says its hitch does not support vertical-hanging bike racks, and CURT 13701 also excludes bike racks that require bikes to hang vertically. Other accessory styles may still require their own fit checks.
Frame dimensions are another potential trap: CURT 13703 and HECASA MO-5981 list fit up to 72 inches, CURT 13701 is specified for frames up to 51 inches, and Buyers Products 1801125 gives a mounting range of 47.5 to 77 inches. These measurements are not interchangeable descriptions of the same fit.
Measure the frame at the intended mounting location and compare it with the exact hitch’s instructions. If the listing omits a dimension or accessory restriction, confirm it with the manufacturer before purchase.
How to Choose a Travel Trailer Receiver Hitch
Frame width and mounting range
Look for a stated frame range that covers the trailer at the hitch’s intended mounting location. CURT 13703 and HECASA MO-5981 list fit up to 72 inches wide; CURT 13701 fits frames up to 51 inches. Buyers Products 1801125 specifies an adjustable mounting range of 47.5 to 77 inches.
Stromberg Carlson CC-300 describes a frame-mounted design but the supplied specifications do not state a width range. These figures favour different situations: a narrower frame may suit the CURT 13701, while a wider or variable installation may point toward an adjustable model with a documented range.
Measure first, and confirm the exact installation dimensions where a listing does not provide them.
Capacity and intended use
Choose a hitch whose documented ratings and permitted use match the job, while respecting the lowest-rated component and frame limits. CURT 13703 and HECASA MO-5981 list 3,500 pounds gross trailer weight and 350 pounds tongue weight; ALMULOO lists the same values. CURT 13701 lists up to 5,000 pounds gross trailer weight and 500 pounds tongue weight, with additional weight-distribution ratings in its product details.
Buyers Products 1801125 lists 3,000 pounds but labels its included receiver not for towing. The higher-rated CURT may suit a buyer who needs its stated capacity and whose frame and other components permit it.
For accessories rather than towing, prioritize confirmed compatibility and installation instead of assuming capacity figures authorize a particular load.
Mounting method and accessory restrictions
Check whether the hitch’s mounting method and accessory limits fit your trailer and plans. Stromberg Carlson CC-300 can be bolted on as Class I or welded on as Class II, while KUAFU GO-1241 describes bolting for Class I and welding for Class II, with different tongue-weight figures by class. CURT 13703 is an adjustable frame hitch, and ALMULOO describes direct bolt-on installation.
For bike racks, note that ALMULOO excludes vertical-hanging racks and CURT 13701 excludes racks that require bikes to hang vertically. Buyers who want a straightforward bolt-on route should verify the specific frame and hardware instructions; those considering welding should confirm that the trailer frame and hitch manufacturer allow it.
Select the rack style only after checking the hitch’s stated restrictions.
Which receiver hitch fits my travel trailer?
For a broad-frame fit with stated capacity, choose CURT 13703 Hitch: it fits compatible frames up to 72 inches and lists 3,500 pounds gross trailer weight and 350 pounds tongue weight. If your frame is no wider than 51 inches and you need the higher listed ratings, consider CURT 13701 Hitch, while observing its vertical-hanging rack restriction. For a travel-trailer or fifth-wheel accessory receiver with a choice of bolted Class I or welded Class II mounting, Stromberg Carlson CC-300 is a relevant option, though the supplied details do not state its capacity.
HECASA MO-5981 Hitch also lists a 72-inch frame fit and 3,500/350-pound ratings. Before deciding, confirm exact frame fit, accessory compatibility, and the limits of the trailer and all connected components.

Frequently Asked Questions
How do I measure my travel trailer frame to confirm receiver-hitch fit?
Measure the frame width where the hitch will mount, using the same reference points specified by the hitch manufacturer. Compare that measurement with the product’s stated fit range, and check mounting-area clearance and frame compatibility. Do not rely on a nominal trailer width; confirm fitment before installation.
Can a receiver hitch mounted on a travel trailer carry a vertical-hanging bike rack?
Only if the hitch and rack manufacturers allow that use. A vertical-hanging rack can place different loads on the receiver than other accessories, and the CURT 13701 has a stated restriction for vertical-hanging racks. Check the specific hitch and rack instructions, plus trailer limits, before carrying bikes.
When should a frame-mounted receiver be bolted on versus welded on?
Follow the receiver manufacturer’s approved installation method and the trailer-frame requirements. The Stromberg Carlson CC-300 is described with a choice of bolted Class I or welded Class II mounting; that does not establish which method suits every trailer. Confirm frame compatibility and installation instructions before choosing.
Do the hitch’s listed weight ratings determine how much my trailer can tow?
No. Use the lowest applicable limit among the hitch, trailer frame, towing vehicle, and other connected components, and follow each manufacturer’s instructions. The CURT 13703 lists 3,500 pounds gross trailer weight and 350 pounds tongue weight, but those figures do not override lower system limits.
What should I verify before using a receiver for a trailer accessory?
Confirm the receiver fits the frame and is approved for your intended accessory and use. Check the accessory’s requirements, the hitch installation instructions, and the trailer’s limits. A receiver intended for a bike rack or cargo carrier should not automatically be assumed suitable for towing or for every rack design.
Final Words
For an adjustable receiver with a broad stated frame fit and listed capacity, CURT 13703 is the overall pick; keep its ratings subordinate to every lower system limit. If your frame is no wider than 51 inches, compare CURT 13701’s higher listed ratings and observe its vertical-hanging rack restriction. Consider Stromberg Carlson CC-300 for its bolted or welded mounting options, but verify its capacity, frame fit, and intended use before installation.
