Sweet setup. I am still using Fasgun Derringers, which are easy to remove and replace when taking the camper on and off. I used to think these were bombproof, and they are, if the installer (me) remembers to use loctite on the threads once the lengths are custom set. Doh. On our last trip to Utah in April, we got down there and did the Cathedral Valley road in Capitol Reef. After the drive, I figured I would check the fasguns since it had been 2500 miles since we reinstalled the camper and I had adjusted their lengths again(a tedious process of installing, removing, cutting the 1/2” eyebolts to length, reinstalling and testing fit - repeat). 3 of the fasguns had completely fallen off, and the last was loose. The camper had shifted 2” to the back, and all the way to one side.
With the help of some fellow campers - and using our long handled shovel for leverage - we got the camper back into position and I reinstalled the fasguns. Next day, we drove to the nearest town that had an auto parts store and bought some loctite and installed them again.
I did NOT think that the eyebolts could turn once installed in the fasguns, but I suppose with sufficient vibration, any thing will eventually fall apart.
5000 miles later - half on rough roads - and they are still secure
