The truck ones would be of a thick, less flexible material. But then again you almost never jam sticks into your trucks boots. I have never tore up a boot( have a lift kit and no gaurds) and nobody I know personally has either. IMHO, you guys abuse the equipment way to much and expect it to live anyway. Just doesn't work that way. When I was into racing, cars and boats, we replaced alot of broken thing caused by the abuse. My street cars and sport boats never had the problems the race gear had. Treat it well and most gear will serve you long and faithfully, abuse it and it will always let you down at the worse possible time.
