1 Pair Universal Bumper Cargo Bracket
This pair provides straightforward bumper mounting for a 4″ square bumper, serving as a practical base for a generator tray or cargo carrier. Best for buyers who want an economical, easy-to-install solution without integrated locking or ventilation features. Limitations include basic support without built-in anti-theft or weatherproofing hardware. Choose this if you need a simple, low-cost mounting option and have compatible brackets already.
ECOTRIC Universal Bumper Cargo Bracket
Designed as a pair, these brackets are suitable for mounting a cargo carrier or generator tray to a 4″ square bumper. Best for users who want reliable, symmetrical support with easy installation. A potential limitation is the lack of integrated weather resistance or security features; you may need additional protective enclosures if exposed to harsh elements. Ideal for RVs that frequently travel and require quick swaps or additions to bumper storage.
Stromberg Carlson CC-220 Gen Secure II
This generator box emphasizes security and ventilation. It includes tie-down rings, an anti-theft design, propane ventilation, and aluminum construction. Best for buyers prioritizing theft deterrence and durable, trailer-ready storage. Better for longer trips or remote locations where security matters more than lightweight portability. Limitation: may be heavier and require more mounting hardware and space than simpler brackets.
Kojem RV Bumper-Mounted Cargo Carrier Kit
The Kojem option is a bumper-mounted carrier designed for campers and RVs, supporting heavy loads with a stated weight-bearing capacity. Best for buyers who need a robust rear storage tray for camp gear or a generator while traveling. Choose this if you require a higher payload and a wider tray than basic brackets provide. A caveat is that the listed weight capacity should be verified with your RV bumper’s specifications to ensure compatibility.
Truck Generator Storage Boxes (Aluminum)
This aluminum toolbox-style storage box offers weatherproofing and a lockable design, making it suitable as a dedicated generator enclosure on trucks, trailers, or larger RVs. Best for users who want a sealed, secure storage solution that protects against rain and dust. Better for applications requiring a standalone enclosure rather than a simple mounting bracket. Limitation: heavier than open-frame solutions, which may affect weight distribution and mounting complexity.
Buying Guide
What should you consider before buying?
- Mounting compatibility: Confirm bumper size (4″ square or similar) and available mounting points on your RV or trailer.
- Protection vs. accessibility: Decide between open brackets for easier access and enclosed boxes for weather and theft protection.
- Weight capacity: Ensure the bumper or tray can support the generator plus any accessories or payload you plan to carry.
- Ventilation: Look for models with venting or space for airflow to prevent generator overheating.
- Security features: For remote use, consider anti-theft designs, locking mechanisms, and tie-down points.
- Materials and durability: Aluminum constructions resist corrosion and reduce weight; steel offers strength but may require coating.
- Weatherproofing: If used in rain-prone areas, prioritize sealed enclosures or splash guards.
Who should consider each option?
- Budget-minded travelers: Basic bumper brackets are quick to install and inexpensive but need additional protection for the generator.
- Frequent movers: Paired bumper brackets with easy installation support flexible mounting for various cargo trays.
- Security-focused users: Enclosed boxes with anti-theft features and ventilation protect valuable equipment on long trips.
- Heavy-load campers: Higher-capacity carriers like Kojem-style trays support larger or heavier generators and gear.
- All-weather users: Aluminum or sealed enclosures provide durability in rain, dust, and road grime.
Installation and compatibility tips
- Read bumper specs: Always verify bumper type, size, and strength with your RV or trailer manufacturer’s guidelines.
- Mounting hardware: Use appropriate bolts, washers, and lock nuts to prevent loosening during travel.
- Vent placement: Position any vents away from exhaust paths and ensure unobstructed airflow around the generator.
- Secure storage: Use tie-downs or latches to minimize movement when driving on rough roads.
