It is suitable for bike racks and cargo carriers with a 2″ shank.

Nilight RV Bumper Hitch Receiver 3500 LBS
Best for: Trailering enthusiasts who want a heavy-duty option with higher weight tolerance while maintaining a bumper-mount design. Useful for campers needing stable bike racks, RV tire racks, or cargo carriers attached to 2″ shank receivers.
Why chosen: It is designed to fit most 4″ to 4-1/2″ continuous steel bumper beams and can be mounted upside down for flexible positioning. The 2″ x 2″ opening aligns with standard bike racks, and installation is straightforward without welding.
Caution: The stated weight capacities depend on the lowest-rated towing component, so confirm compatible elements like racks and hardware to avoid exceeding limits.

Why chosen: The kit emphasizes versatility, enabling mounting on cargo boxes like the Cargo Caddy. It includes hardware to stabilize two bikes, expanding carrying capacity for family trips or multi-bike adventures.

Why chosen: The unit is lightweight (about 5 lbs) and easy to assemble. Its rack design accommodates square, round, and oval bars up to 3″ wide, enabling multiple units on a single vehicle for extra capacity.
Limitation: Roof-mounted trunks can add wind resistance, and it is limited to one bike per rack. Consider secure locking and weather exposure for longer trips.
Buying Guide: Bolt-On Bike Carrier Essentials
What to consider when selecting a bolt-on bike carrier for an RV or trailer:
- Mounting compatibility: Confirm bumper beam dimensions (4″ to 4.5″ are common) and ensure the 2″ x 2″ hitch opening matches your rack shank.
- Weight capacity: Check tongue weight limits and gross trailer weight in relation to your bikes and racks. The lowest-rated component governs safety.
- Intended use: Decide between bumper-mounted and roof-mounted options based on vehicle height, ease of access, and wind considerations.
- Installation ease: Look for kits with pre-threaded bolts and straightforward mounting procedures to minimize installation time.
- Weather and durability: Stainless or coated steel offers corrosion resistance; consider rust protection for coastal or humid environments.
- Future expandability: If you plan to add more bikes or cargo, choose adapters or dual-bike kits that pair with your existing cargo system.
- Security considerations: Some units require hitch pins or locks (not always included). Plan for securing racks and bikes against theft and vibration.
