Finally, the photo...
I have a Max Coupler, and on a recent trip I had to re-torque the bolt 3 times over the course of 6 weeks because it kept loosening. Once it was loose enough that I didn't feel comfortable driving and had to leave the trailer and drive into Ouray (I was part way up Imogene Pass) to tighten it (I don't carry two 1 1/2" sockets). The first two times I used the top end of the specified torque range (100 ft-lbs). The last time I used 150 ft-lbs, and it appears to be loosening again.
Has anyone else had this problem? I am considering just getting a regular split lock washer/nut and tack welding it to the bolt after torquing. Good idea? Other suggestions? As you can see from the design, of this bolt lets go, not good!
