Quite a few years ago Dw and I stopped at a mall to get some last minute items on our way out of town. While in the store someone pulled our pin and unhooked the 5th wheel hitch. We hopped in and started to pull away and down she came (no damage, not even a scratch). Two mods came out of that: 1) a small pad lock on the handle that engages and disengages the receiver 2) took a cheap cutting board and cut it into one inch strips. Counter sunk some holes and screwed to the underside of my 5th above the truck bed. Never did happen again but was ready if it did.
