I ALWAYS had to retighten them after 4 or 5 hours of setting up camp.

I'd never rely on them to stop the trailer from rolling. They are not an alternative for correctly chocking the tires. Just movement inside the trailer has caused my X-Chocks to fall out of position, leaving the trailer totally "unchocked and prepared to roll"..... YMMV

Hey John, after reading about your experience with X-Chocks I'm reconsidering purchasing a pair. Our campsite this past June had a significant slope and in the photo you can see a stout log under the left rear stabilizer jack because it wouldn't reach the ground. The tongue jack was down as low as possible and we still weren't level, but close enough for the fridge to be okay. All four wheels were rubber chocked but it was still a hold-my-breath moment when I unhitched. Thankfully nothing moved during our 5-night stay. My thoughts were to use a pair of X-Chocks if in a similar situation for peace of mind but it doesn't sound like they do much more than prevent a little fore/aft motion. Is this the general consensus on X-Chocks? They stop some rocking motion but are not considered a supplement to chocks regarding any significant trailer movement?
