Andersen levelers and question about x-chocks

Dang the rotten luck!!!! Just bought a pair of Andersen levelers and wouldn't ya know it, our campsite is almost perfectly level. I mean really, how many times do you get a site that you don't need anything to level? LOL

As to the x-chocks. When ever I first put them on I tighten them as tight as I can. I go back an hour later and most times I can remove them easily. Do any of you have that same problem? Thanks, John
