This is a great thread. Apparently there really is more than one way to skin a cat...or turnbuckle. When I first got my camper, I checked the buckles after the first couple hundred of miles and they were fine. But since then, there have been a few times that they have been loose, but I've never had one unhook. Still, I check them all the time now so I'd like some piece of mind. I've driven for hours on wash board (stutter bumps as my dad called 'em) and I think my truck/camper will never be the same after all those miles of rattling. I think I'll try Ron's zip ties first as it seems pretty easy to do. I'll go from there with some of the other ideas. There are some ties on Amazon that I'd be happy to share, but for some reason, I can't paste anything I copy onto WTW. They are called buycableties 22" HD (250lb) ties.
