Brophy Clamp-Ons and Aluminum Truck Beds?

I used the Brophy's with my Coachman Ranger. I think the weight loaded was probably 3500 pound. Once I figured them out I didn't have a problem with them. I had my Chevy Silverado dually so the weight was not a problem for the truck or the mounts for that matter. The rear mount touched the fender well of the dually tires. I was putting the foam strips that came with them on but it was still wearing away. What I did was I used 3M double sided tape and that worked perfectly. It didn't wear anymore, heat gun would take the tape right off. I also had a fabricated trailer mount of sorts that slid into the receiver and mounted to the underside of the camper with nuts and bolts, there were two mounted rings that I installed on the underside of the rear of the camper and it held the whole thing in place. The rear mount was a leftover from my dads 1966 Beeline TC that became my first truck camper. The mount looked like this, sorta.

We never had any trouble with the Brophy's. Good luck!
