Best for: RVers who have slightly larger bumper beams (4″ to 4-1/2″) and want an easy-install solution for attaching bike racks or cargo carriers. This model uses 4 full threaded bolts and nuts for a straightforward mount. It offers a 200 lbs tongue weight capacity and includes no hitch pin or lock by default. It’s suitable for mounting on most bumpers with a 4″ to 4.5″ continuous beam and can be inverted if needed.
Why chosen: This option focuses on simple, mechanically robust installation with clear compatibility to a wider bumper size range. It’s a solid pick for users who prioritize installation speed and a reliable 2″ receiver, with the caveat of lower tongue weight compared to higher-capacity models.

It can be mounted upside down, supporting a variety of accessories like bike racks or cargo racks, and installation does not require welding.

Buying Guide: What to Consider When Choosing an RV Bumper Hitch Receiver
- Compatibility: Confirm bumper size (usually 4″ x 4″) and ensure the receiver is designed for 2″ x 2″ shanks. Check if the unit can be mounted upright or inverted on your bumper.
- Weight Capacity: Review tongue weight (TW) and gross trailer weight (GTW). Select a receiver that matches or exceeds the weight of the intended accessories, not towing needs.
- Mounting Style: Bolt-on versus welded installations. Bolt-on options are easier and more versatile but may require precise hole alignment and hardware.
- Wear and Finish: Powder coating and corrosion resistance are important for long-term outdoor exposure, especially in salted or wet environments.
- Included Hardware: Some products include hitch pins, clips, or mounting bolts. Consider whether you need these accessories to complete installation.
- After-Sales Fit: Look for compatibility with a wide range of accessories like bike racks, cargo carriers, tires racks, or shelves to maximize storage capacity.
