I just made myself a free one that works just as good as our old X-chocks ...
I took a scissor jack from my wife's old Toy*ta's trunk and cut a piece of 4"X4" into two 45 degree chocks, drilled the ends of the jack and screwed some decking screws into them from the inside out. Works better than our old, broken X-chocks ever did, it was free and no more rocking in the TT!! I'll attach some pictures. It was quick, easy and cheap. Heck it was free! I had everything sitting in my garage! I will make a second one just in case I experience any shaking in our next outting. Hope this helps. And I hope the pictures actually attach this time.
