Stromberg Carlson CC-255 Trailer Tray – A-Frame Mounted Tray

This A-frame mounted tray is designed for RVs and travel trailers, placing gear over the softest riding area for stability. It is ideal for transporting a generator, cooler, bikes, or tools while freeing interior storage. The unit supports up to 300 lbs, making it a strong option for bulky equipment. The curved-leg design aims to fit a wide range of A-frame trailers.
Best for: RV owners with A-frame setups who want a high-capacity, stable exterior storage solution. Choose this if you need a robust cargo rack that mounts on the trailer’s A-frame and can handle a generator without sacrificing interior space.
Caution: Ensure your A-frame dimensions are compatible and that mounting hardware aligns with your trailer frame to avoid interference with hitch components.
STROMBER Trailer Tray

The STROMBER Trailer Tray is described for compatibility with multiple makes and models. It emphasizes fitment information to help buyers determine whether it will work with their trailer. It weighs 68 lbs, indicating a substantial, steel-based construction suitable for outdoor use and variable cargo.
Best for: Buyers who want a flexible tray that can adapt across several trailer brands with guidance on fitment. If you need a mid-weight tray that can take gear without a heavy installation, this could be a practical pick.
Caution: Verify precise fitment for your specific trailer model, as compatibility can vary widely among makes and years.
Stromberg Carlson CC250 Trailer Tray

The CC250 is a trailer tray with integrated shelving, tool holders, and storage solutions designed to optimize external cargo on travel trailers. It highlights a system approach to organizing tools and equipment for easy access while on the road.
Best for: Trailer owners who want convenient external storage with built-in shelving and tool holders. This tray helps keep equipment organized and ready for use without opening the trailer interior.
Caution: Check the overall footprint to ensure it fits your tongue area without interfering with propane lines or plumbing located near the hitch.
ONLYLIDA Heavy Duty Steel Sliding Tray (24″x24″)

This heavy-duty steel tray provides a reliable mounting platform for heavy gear outside the RV, including batteries, generators, and toolboxes. Its universal frame compatibility makes it a versatile choice for many trailer types and mounting configurations. The sliding feature facilitates easy access to equipment in tight spaces.
Best for: RV owners needing a secure, sliding exterior tray with high capacity for heavy equipment. Use this if you prioritize easy reach to generators or batteries from outside the RV door or storage compartments.
Caution: Confirm sliding mechanism clearances on your trailer to avoid rubbing against taillights, doors, or other exterior hardware during operation.
ONLYLIDA Heavy Duty Sliding Tray (24″x14″)

The 24×14 option shares the same rugged construction and universal frame compatibility as the larger tray, but in a more compact footprint. It supports heavy gear and provides secure mounting for tools, batteries, and outdoor equipment while staying inside a smaller external area.
Best for: Buyers with tighter trailer layouts or those needing a lower-profile exterior tray for generators and tools. Choose this if space is constrained but you still require reliable heavy-duty support.
Caution: The smaller dimension means a slightly reduced gear capacity; ensure your generator or batteries fit within the 24×14 footprint before purchase.

The MORryde SP60-047 offers 100% extension and a 250 lb weight capacity, with ball bearing slides for smooth operation. This tray is designed to expose a generous amount of external storage, suitable for frequently accessed items like generators or batteries placed on long slides during travel.
Best for: Those who value full extension for easier loading and unloading of generator or heavy gear without stepping outside. It suits frequent-access scenarios where reach matters.
Caution: Check installation space under the trailer to ensure full extension doesn’t collide with ground, or with hoses and wiring beneath the unit.
Let’s Go Aero CargoTray Add-On

The CargoTray Add-On is designed to integrate with the Jack-IT system for versatile storage on trailers, including bikes and utility gear. It emphasizes robust steel construction and two-position adjustment for propane tank access, which can be a practical feature when using a trailer with propane needs.
Best for: Owners who want a flexible add-on tray that can adapt to different configurations, including bike transport and propane access. Consider this if you already use Jack-IT or need an adaptable exterior tray with multiple mounting options.
Caution: Confirm compatibility with your current hitch system and any auxiliary equipment mounted on the trailer roof or bed to avoid interference.

Best for: RV owners who need a dedicated outside-access generator tray with secure latching. Choose this if generator accessibility and security during travel are top priorities.
Caution: Ensure the generator dimensions are compatible with the tray and that the mounting location can support the intended weight along the entire travel path.
Buying Guide: Key Considerations For Trailer Trays
- Trailer compatibility: Confirm frame type (A-frame, tongue, or universal) and mounting points. Some trays are designed specifically for A-frame trailers, while others are adaptable to multiple setups.
- Weight capacity: Compare load ratings to ensure the tray supports your generator, batteries, and tools. Overloading can affect handling and frame integrity.
- Access and ease of use: Sliding trays offer easy reach for heavier gear. Consider extension length and clearance when the trailer is parked or detached.
- Storage organization: Look for built-in shelves, tool holders, or shelving to maximize space and keep gear organized outside the trailer.
- Durability and finish: Steel construction with corrosion-resistant coatings helps withstand outdoor exposure, road debris, and weather.
- Installation and clearance: Check for potential interference with hitch components, propane lines, taillights, or doors. Measure and plan before purchasing.
- Versatility: Some trays are modular or compatible with other carriers and accessories, offering a scalable storage solution for bikes, tool chests, or propane equipment.
