used to use the x chock. my 5th had 15" now 16 " not enough space for easy use. it came with 1 PAL wheel chock. should I need two. these spread to fit under wheel. are they as good.
I hope and pray nothing ever happens to my rotochoks. Thet are probably the best RV investment I have ever made. I was lucky enough to get mine before they went out of businees
