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 had also had little space for x-chocks, too. I went with the Equalizer One-Step. They have a lot of adjustability allowing for some tight fits, and they're easier to use than x-chocks.
