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

Best for: RV owners seeking an upgrade to trailer storage without sacrificing the A-frame’s ride. This tray attaches to the A-frame, placing gear where the ride is smoothest, and supports bulky items up to 300 lbs. It doubles as a reliable carrier for generators, coolers, bikes, and tools, expanding usable travel trailer storage. The curved-leg design aims to fit a wide range of A-frame configurations with a custom-like fit.
Why chosen: It directly addresses the need to carry a generator on a trailer while keeping weight distributed over a stable, low-ride area. The high weight capacity supports a typical portable generator or other bulky equipment.
Caution: Verify your A-frame dimensions and clearance before installation, as some trailers may require additional mounting hardware or adjustments.
MaXpeedingrods 3500 Watt Portable Inverter Generator

Best for: Users needing a compact, lighter-weight power source for home backup, outdoor camping, or RV use. With 3500 peak watts and 3000 running watts, it powers common appliances and RV setups, and its Eco mode extends runtime. Port selections include a 30A RV outlet, two 20A outlets, and USB ports for USB devices.
Why chosen: It offers a practical balance of output and portability, making it a versatile option for trailers where space and weight matter. The multiple outlets simplify powering several devices at once.
Caution: The weight and size are still a consideration for mounting on some trailer setups; ensure secure transport and ventilation around the unit during travel.
Kojem RV Bumper-Mounted Generator Carrier

Best for: Campers and trailer owners who need extra storage outside the bumper area. This carrier adds space for a generator, luggage, tools, and outdoor gear without crowding the interior. It accepts multiple trays to extend width up to 8 feet for larger payloads.
Why chosen: The bumper-mount design and high cargo potential make it ideal for expanding trailer cargo capabilities without sacrificing interior space.
Caution: Check bumper compatibility with your trailer and confirm available tie-down points to avoid interference with towing or clearance issues.
EF ECOFLOW TRAIL 300 DC Portable Power Station

Best for: Camp groups, families, or travelers who need a compact power source with several output options. The 288Wh capacity and 300W output support essential devices, and the built-in camping lamp adds convenience for overnight stops.
Why chosen: This unit is especially suitable when a trailer-based power solution must be lightweight, portable, and easy to deploy at campsites or emergencies.
Caution: For high-wattage devices, monitor runtime and avoid loading beyond the output limits. It’s ideal for lighter appliances and electronics rather than heavy appliances.
MECMO NEMA L14-30P to 14-50R Adapter

Best for: Trailer owners who need to connect generators with different outlet standards to their RV power cords. This adapter converts a 30A locking generator plug to a 50A RV receptacle for broader compatibility.
Why chosen: It provides a practical bridging solution when pairing generators and trailers with mismatched outlets, enabling safer and more flexible power delivery.
Caution: Use within the electrical ratings (max 30A overload for the generator side) and follow safety guidelines to prevent overheating or arcing.
Buying Guide
What type of buyer should consider a trailer-ready power solution? Look for a setup that aligns with vehicle compatibility (A-frame, bumper mount, or hitch-mounted), intended load, and travel style. If you frequently tow and store gear, prioritize secure mounting, weather resistance, and weight distribution. For campers and RVers, consider how much power you truly need and whether you require a full generator, a portable inverter, or a compact power station.
Key considerations and comparisons:
- Mounting compatibility: A-frame trays fit many travel trailers; bumper-mounted carriers work well for exterior storage but require bumper specifications.
- Power needs: Heavy loads (air conditioners, microwaves) demand higher wattage; lighter devices suit smaller generators or power stations.
- Weight and transport: Heavier units require sturdy mounting and secure tie-downs to prevent movement during travel.
- Outlets and versatility: RV outlets, USB ports, and DC ports determine how many devices you can run simultaneously.
- Durability and weather: Aluminum and rust-resistant builds offer longer life in outdoor environments.
- Safety and compliance: Locking connectors, correct wiring, and proper ventilation reduce risk of electrical faults.
Frequently Asked Questions
- Can I mount a generator on my travel trailer A-frame? Yes, using an A-frame trailer tray designed for generators and heavy gear, ensuring the load is balanced.
- What size generator is best for RV use? A generator with 3000–3500 running watts covers most RV essentials; larger models provide more headroom for appliances.
- Are portable power stations a good substitute for generators on trailers? They’re compact and quiet, suitable for charging devices and small appliances, but may not power high-wattage devices without frequent recharging.
- Do I need adapters to run a generator on an RV? If your generator outlet doesn’t match your RV cord, a locking adapter (like L14-30P to 14-50R) can bridge the gap safely.
- What is a safe way to transport a generator on a trailer? Secure mounting, use appropriate tie-downs, avoid obstructing towing components, and ensure ventilation to prevent overheating.
- Is a dedicated generator box necessary? A generator box like Gen Secure II adds anti-theft protection and weather resistance while keeping the box compatible with existing trailer trays.
