Buying Guide
What mounting style fits your trailer best?
- A-frame trays offer close-to-front access and balanced weight distribution on travel trailers; they’re ideal when you regularly carry generator or tool storage near the nose of the trailer.
- Bumper-mounted kits and hitch trays provide flexible, removable setups and work well on trailers or vehicles with rear access constraints.
How much weight and what kind of gear will you carry?
- Higher weight capacities are important for generators, heavy tool boxes, and multiple storage bins. Always verify the combined weight with any additional items on the tray or bumper.
- Consider corrosion resistance and weather protection if you operate in humid or coastal environments.
How easy is installation and removal?
- Adapters with adjustable arms and quick-release pins speed up setup and removal, especially for seasonal use.
- Check compatibility with your trailer frame, bumper, or receiver size to avoid fitment issues.
Security and durability matter too.
- Anti-theft designs are beneficial for unattended storage while on the road or parked at destinations.
- Aluminum or coated steel construction helps resist corrosion and extend life in varying climates.
Frequently Asked Questions
- What is the best mount for a travel trailer with an A-frame?
- For frequent generator use, should I choose a Gen Secure II box or a simple tray?
- Can I mix and match a generator box with any tray?
- What safety checks should I perform after installing a cargo mount?
- Do I need special tools to install these racks?
- Is a bumper-mounted option better for quick removal?
Answer: The best option depends on your trailer design and usage. A-frame trays like the CC-255 provide front access and strong support for bulky gear, while Gen Secure II boxes add security for stored items. Bumper-mounted mounts offer modularity and easier removal, and hitch-mounted trays maximize interior cabin space when you don’t need front access. Always confirm trailer compatibility, weight limits, and installation requirements before purchasing.
