Review on Maximize Towing Capacity with CURT 19100 Camper RV Bumper Hitch: 4-Inch Beam, 2-Inch Receiver, 3,500 lbs by Jeff Payne

This is a solid 2" bumper mount receiver. My unit had one side 1/16" smaller which made installation more difficult but still worked. The bolts used for this assembly are also designed for high loads. I used black tape on my bumper under the bolts to protect the bumper from abrasion from the bolt threads. Installation took about 10 minutes (it would be even less if both sides of the device were the same width).
