Review on 🚚 HITOWMFG Drop-Down Bumper Receiver Adapter - 2-inch Size for 4x4-inch Bumper Trailers, Towing Cargo Carriers, and Bike Racks by Joseph Stone

Arrived a day early and fits great. I installed it on a 2019 Forrest River 26ft RV with a 4" x 4" rear bumper. The hitch is actually spaced out about 1/8 inch so it slides right through. Nice accessories included. Nuts are serrated lock nuts and require a 19mm deep head. A deep 3/4 hex shoe will also work (ask my teenager who helped me install it :)). After tightening the nuts, the small gap was almost gone and the hitch was tight to the bumper. We're going on a trip with a bike rack this weekend, let's see how it works. See pictures for clarity.
