Best Generator Tray For Trailer: 9 Options Compared

#1 · Best Overall

1. Stromberg Carlson CC-255

• Dimensions: 35.98 x 24.02 x 5 in
• Weight: 62 lb

Best for: A-frame travel gear carrier.

Why it ranks #1: Made for A-frame mounting and lists a 300-pound gear capacity, making it the clearest match for carrying a generator on a travel trailer.

The Stromberg Carlson CC-255 mounts to an RV’s A-frame and supports up to 300 pounds, putting bulky cargo over what the listing calls the trailer’s softest-riding area. That placement can free interior storage for travel while carrying equipment such as a generator, cooler, tools, or kids’ bikes.

Its 35.98-by-24.02-inch tray offers a defined platform for gear, while the A-frame mounting position keeps that cargo at the trailer front rather than inside living or storage space. The 300-pound capacity accommodates substantial equipment, and the maker identifies generators, coolers, bikes, and tools as possible loads. At 62 pounds, the tray itself is a substantial component to handle during installation or removal, so plan for that weight when arranging the mounting work.

Skip it if you need a pull-out tray inside an RV compartment; MORryde SP60-044 offers full-extension access to batteries.

Choose this for an RV owner who wants a front-mounted platform for a generator or mixed travel gear. Its A-frame position and 300-pound limit are key considerations, as is handling the 62-pound tray.

#2 · Adjustable A-Frame

2. KUQAE A-Frame Tray

• Weight: 40 lb

Best for: Adjustable mixed-gear storage.

Why it ranks #2: Designed as an A-frame tray for generators and other camping gear; adjustable height and width help accommodate equipment of different sizes.

KUQAE’s adjustable-height and adjustable-width tray lets owners reconfigure storage around different-sized equipment, making it useful when the load changes between trips. The listing names generators, bikes, coolers, spare tires, tools, and camping gear as intended cargo, with the tray serving as an accessible outdoor storage area.

The height and width adjustments allow the layout to be changed for varied gear, which can help organize a changing mix of camping equipment instead of committing to one fixed arrangement. Its recommended uses span generators, bikes, coolers, spare tires, tools, and outdoor equipment. The supplied specifications list a 40-pound item weight and include one trailer tray; they do not provide a load-capacity figure, so the listed versatility does not establish a safe maximum load.

Skip it if you need a stated load rating before choosing a generator platform; Stromberg Carlson CC-255 lists a 300-pound capacity.

Consider this for an RV owner whose outdoor cargo mix varies and who values adjustable tray dimensions. The listing names many gear types, but buyers who need a stated maximum load should account for the missing capacity figure.

#3 · Bumper-Mount Option

3. Kojem Bumper Carrier

Best for: Bumper-mounted trailer cargo.

Why it ranks #3: A trailer-compatible steel carrier rated for 200 pounds, with fitment listed for several bumper sizes and multiple tie-down points.

Kojem’s steel carrier mounts to compatible RV bumpers and provides a 200-pound cargo capacity, creating exterior storage for gear that would otherwise occupy trailer space. The listing says it fits most campers, trailers, and RVs with bumper sizes including 4.0, 4.5, 5.3, and 6.0 inches.

Its bumper-mounted arrangement adds storage at the trailer rear, and dozens of tie-down points give users multiple places to secure luggage, tools, and outdoor gear. The steel carrier weighs 15 pounds and has a stated 200-pound load capacity, giving buyers both its own handling weight and cargo limit to consider. Mounting hardware is included. Because fit is described by bumper sizes, the bumper configuration is a key part of deciding whether this exterior carrier suits a particular trailer.

Skip it if you need a sliding tray inside an RV compartment; MORryde SP60-044 uses full-extension slides for battery access.

Choose this for a trailer owner seeking rear-mounted storage for luggage, tools, or outdoor equipment. Its 200-pound capacity and tie-down points suit cargo carrying, while bumper size and configuration remain central fit considerations.

#4 · Highest Capacity

4. QTSZNDF Generator Slide Tray

• Dimensions: 25.9 x 14.9 x 3.9 in
• Weight: 22 lb

Best for: High-capacity narrow slide-out.

Why it ranks #4: Explicitly identifies generator use and lists a 264-pound capacity, full-extension ball-bearing rails, and a locking mechanism for travel.

QTSZNDF’s full-extension ball-bearing rails and 264-pound capacity combine to bring heavy equipment out of an RV basement compartment while keeping it locked during travel. The 22.6-by-13-inch platform is a relatively narrow stated surface for a generator or other listed heavy cargo.

Full-extension rails pull the platform outward, giving access to equipment without crawling into a dark storage space, as the listing describes. A built-in locking mechanism helps keep the load stable during travel, while the 264-pound capacity establishes a clear weight limit for choosing equipment. The platform measures 22.6 by 13 by 1.9 inches, so its usable surface is an important consideration when assessing generator dimensions and how the load will sit.

Skip it if you need a roughly 24-inch-square tray surface; ONLYLIDA’s 24-by-24-inch steel slide offers a wider stated platform.

This suits an RV owner with heavy equipment in a basement compartment who wants full-extension access and a travel lock. Check the generator’s footprint against the 22.6-by-13-inch platform before selecting it.

#5

5. ONLYLIDA Sliding Tray

• Weight: 31.3 lb

Best for: Steel pull-out utility platform.

Why it ranks #5: A steel slide-out platform specifically lists portable generators among supported gear, though the supplied specifications do not state a load capacity.

ONLYLIDA’s solid-steel sliding tray combines a 24-by-24-inch platform with a 2.7-inch profile, offering a pull-out storage surface for heavy equipment without placing it in the RV living area. Its listed uses include batteries, portable generators, toolboxes, fuel cans, and other outdoor gear.

The sliding format brings equipment outward for access, while the steel construction provides a stable mounting platform for the heavy items named in the listing. At 24 by 24 inches and 2.7 inches high, its stated dimensions give buyers a concrete footprint to compare with a storage or mounting area. The open-tray design supports carrying gear outside the living space, but the supplied information gives no maximum load figure for assessing heavier generator setups.

Skip it if you need a published load limit for heavy equipment; YANZLAROX’s 24.5-inch sliding tray is rated for 200 pounds.

This suits RV owners seeking a steel pull-out platform for a generator, battery, or utility gear outside the living space. Check the stated 24-inch footprint against the intended mounting area, and note that no load rating is supplied.

6. YANZLAROX Sliding Tray

• Dimensions: 24.5 x 24.5 x 2.75 in
• Weight: 31.5 lb

Best for: Rated full-extension service tray.

Why it ranks #6: Its reinforced steel tray supports up to 200 pounds and locks for travel, with full extension for generator maintenance and equipment access.

YANZLAROX pairs full-extension, dual ball-bearing slides with a 200-pound capacity, letting users pull equipment out for battery wiring, generator maintenance, or access. Six access holes also let installers reach the base mounting points without removing the slide rails, simplifying the described mounting sequence.

The 24.5-by-24.5-inch tray has a 2.75-inch overall height, while its listed inner dimensions are 21.8 by 23 by 1.9 inches; those measurements help assess equipment and compartment clearance. Full extension makes wiring and maintenance access easier, and the mechanical lock secures the tray for travel. Six access holes allow fastening with the rails assembled, avoiding a step of removing and reinstalling them during installation.

Skip it if you need an exterior A-frame cargo platform rather than compartment access; Stromberg Carlson CC-255 mounts on an RV’s A-frame.

Choose this for an RV owner who needs to reach a battery or generator for service without crawling into a compartment. Compare both inner and overall dimensions with available clearance before planning the installation.

#7

7. Prismora Sliding Tray

• Weight: 30 lb

Best for: Strapped compartment cargo tray.

Why it ranks #7: The pull-out tray lists portable generators among its uses and includes straps, but its stated 24.5-by-24.5-inch dimensions require compartment-fit checks.

Prismora’s sliding steel tray comes with straps, giving RV owners a way to secure listed cargo such as batteries, portable generators, toolboxes, and fuel canisters. Its 24.5-by-24.5-by-2.75-inch overall dimensions define the space it occupies as a pull-out storage solution.

The sliding format provides pull-out access to equipment, while the included straps add a means of securing cargo on the tray. Prismora lists ten pre-drilled mounting holes and a screw-mounted installation, which gives installers designated points for fastening the base. The tray is also identified for batteries, generators, toolboxes, and fuel canisters. Its overall dimensions are provided, but no load-capacity figure appears in the supplied details, leaving maximum supported weight unspecified.

Skip it if you need a specified load rating for heavy cargo; MORryde SP60-044 lists a 250-pound maximum recommendation.

This fits an RV owner looking for a strapped pull-out tray for equipment stored in a compartment. Its dimensions and ten-hole mounting layout help with planning, but buyers should weigh the lack of a stated capacity.

#8

8. MORryde SP60-044

• Dimensions: 24.25"L x 24.15"W x 2.75"H
• Weight: 12 lb

Best for: Simple full-extension battery access.

Why it ranks #8: A 250-pound-rated, full-extension tray with ball-bearing slides could ease generator access, but its stated recommended use is batteries.

MORryde’s 100-percent-extension ball-bearing slides pull an RV battery tray fully outward, making battery access easier without reaching into a dark compartment. The 24.25-by-24.15-by-2.75-inch metal tray supports up to 250 pounds, and its powder-coated finish provides a durable black surface.

Full extension brings the battery into reach, while ball-bearing slides support the tray’s outward movement. The 250-pound maximum recommendation gives a weight boundary for battery loads, and the 24.25-by-24.15-inch footprint helps assess the mounting space required. No assembly is required, so the tray arrives without an assembly step before installation. Its stated recommended use is battery storage, making it a focused choice for RV owners who prioritize access over a multi-purpose cargo platform.

Skip it if you want an A-frame platform for generators and mixed travel gear; Stromberg Carlson CC-255 supports up to 300 pounds.

This is a fit for RV owners seeking straightforward, full-extension battery access from a compartment. Its 250-pound limit, battery-focused recommendation, and 24.25-by-24.15-inch footprint define the relevant load and space considerations.

#9

9. IronFangX Double-Layer Tray

• Dimensions: 25.2"L x 24.23"W x 4.33"H

Best for: Two-tier compartment organizer.

Why it ranks #9: Its double-layer design creates extra storage and a secondary tray supports up to 10 kilograms, but the supplied details do not establish generator capacity.

IronFangX’s double-layer pull-out design adds a separate secondary tray for smaller items alongside the main storage area. That divided layout can keep hand tools, snacks, or camping accessories apart from heavier gear in an RV or pickup compartment, while the listing specifies a 10-kilogram limit for the secondary tray.

The 25.2-by-24.23-by-4.33-inch steel assembly uses two pull-out levels to separate small accessories from larger equipment, making the compartment easier to organize. The secondary tray is rated to support up to 10 kilograms, a useful boundary when deciding which items belong there. Ratchet straps are identified as a special feature for securing cargo, and the alloy-steel construction provides the stated material basis for this storage setup. Care instructions call for wiping with a damp cloth.

Skip it if you need a stated 200-pound rating for a single-level slide; YANZLAROX’s 24.5-inch tray is rated to that capacity.

Choose this for an RV or pickup owner who wants smaller accessories separated from larger cargo in a compartment. Keep the secondary tray’s 10-kilogram limit in mind when assigning tools or supplies.
