I bought this wheel chock to fit into a trailer bed during our recent 1400 mile cross country move. Unfortunately you are limited in the mounting options as the 4 holes are carved into the stone. Due to the trailer's alternating wooden and metal bottom, I had to mount a narrower board, but the holes in the stop were too wide. It would make more sense if the mount had alternative mounting holes (e.g. a TV wall mount). I'm sure it would be a good product if I could use it. Looks solid and high quality, but it's good to know if there are any limitations. Standard bolts and nuts are also included. Even if it would fit my trailer, I would have to buy hitch bolts with no access to the bottom of the truck.
