I believe there are two, maybe three, sizes of x-chocks. My friend has a Bigfoot, and the tires are close together. He has a very compacted set that gets into narrow places. May be a different brand, but looks very similar to BAL x-chocks. They also make "extended fit" x-chocks that fit tires that are farther apart than normal. I don't know the specific dimensions for these.
