Stromberg Carlson CC-255 Trailer Tray

Best for: RVs with A-frame trailers needing extra space for generators, coolers, and tools. This tray mounts over the trailer’s soft-riding area, maximizing storage without sacrificing tow stability. It supports up to 300 lbs, making it suitable for compact generators and bulky gear. The curved-leg design adapts to many A-frame configurations for a snug fit.
Why selected: It balances capacity and universal fit with a simple installation, offering a dedicated cargo rack that frees interior space. The tray’s stability helps prevent shifting during travel, an important factor when carrying heavy equipment.
Caution: Ensure the A-frame’s structural integrity before mounting and verify that the total load does not exceed trailer limits. Overloading the tray can affect handling and sway in certain tow conditions.
MaXpeedingrods 3500 Watt Portable Inverter Generator

Best for: Campers and travelers needing a compact, lightweight power source for small loads at remote sites or on the road. With 3500 peak watts and 3000 running watts, it powers essentials without heavy bulk. A 47-pound frame makes it easy to transport and stash near a trailer.
Why selected: Its Eco mode extends runtime, and multiple outlets (1x 120V 30A RV outlet, 2x 120V 20A outlets, 2x USB) support a range of devices. This makes it a versatile option for keeping essentials powered during longer outings or emergency use.
Caution: The unit’s running wattage is suitable for smaller loads; larger appliances may require a bigger generator or staged usage to avoid overloading.
Kojem RV Bumper-Mounted Cargo Carrier

Best for: Campers with bumper-equipped trailers seeking additional cargo space. This carrier weighs about 15 pounds and can carry up to 200 pound-feet, providing a flexible platform for luggage, tools, or outdoor gear.

Why selected: The option to add more trays creates a scalable storage solution, making it ideal for longer trips with more equipment. It’s a simple way to extend trailer capacity without sacrificing interior space.
Caution: Check bumper capacity and mounting hardware compatibility with your trailer to avoid misalignment or overloading the bumper assembly.
EF ECOFLOW Trail 300 DC Portable Power Station

Best for: Groups or families needing emergency and camping power with a compact footprint. The 288Wh capacity supports multiple devices with five output ports, including USB-C PD for fast charging. A built-in camping lamp with adjustable brightness adds practical illumination for outdoor use.
Why selected: Its multiport design and high-port versatility let users power lights, phones, and small appliances from a single unit. The rugged build and water resistance enhance reliability in outdoor environments.

It is designed to fit with Stromberg Carlson CC-255 trailer trays and bumper adapters, providing a cohesive security solution.
Why selected: The anti-theft design adds peace of mind during travel and storage, while the durable aluminum construction withstands outdoor conditions. It effectively pairs with trailer-mounted trays for a secure generator enclosure.
Caution: Ensure proper ventilation to avoid heat buildup and follow safe exhaust practices when in use to prevent fumes from accumulating in enclosed spaces.
Buying Guide: How To Choose A Trailer Generator Setup
What mounting style fits your trailer best? A-frame trays are ideal for trailers with a front cross member, while bumper-mounted carriers suit trailers with robust bumper frames. Consider stability, weight capacity, and how often you plan to move gear between the trailer and site.
How much power do you need? For basic camping and backup, a 2000–3500W generator or a compact inverter may suffice. For extended trips with multiple devices, aim for higher running watts and consider multiple power sources, such as a portable power station alongside a traditional generator when appropriate.
Security and weather protection matter. If you transport valuable gear, a dedicated generator box with anti-theft features and rust-resistant materials can prevent exposure to the elements and theft. Ensure proper ventilation for any enclosed storage solutions.
Portability and convenience. Lightweight, easy-to-move components help when you frequently load and unload gear. Look for modular options that allow future expansion, such as additional trays or compatible accessories.
Connectivity and outlets. Ensure the generator or power station has the required outlets for your devices (RV outlets, USB, USB-C PD, 12V ports). Confirm compatibility with your trailer’s electrical system and campsite electrical hookups.
Frequently Asked Questions
- What is the safest way to mount a generator on a trailer? Use purpose-built trailer trays or bumper mounts designed for generator weight, and follow manufacturer installation instructions. Secure with tiedowns and ensure proper ventilation around exhausts.
- Can I run a generator directly on a trailer while driving? Generally not recommended due to exhaust and vibration. Use a trailer-mounted setup primarily for storage and occasional stationary use at campsites.
- What should I consider for generator ventilation? Ensure adequate clearance around the generator to prevent heat buildup and ensure exhaust outlets are not obstructed by the trailer or cargo.
- Is a portable power station enough for camping? For light to moderate loads, a 288Wh power station can power lights, phones, and small devices. For heavy appliances, supplement with a larger generator or additional power sources.
- How do I secure gear stored on a trailer tray? Use tie-downs, bungee straps, and cargo nets. Ensure all items are balanced and fastened to prevent shifting during travel.
- Are anti-theft generator boxes worth it? Yes, for RVs and trailers that park in public areas. They provide an extra layer of security while still allowing ventilation and access for maintenance.
