Sean, I bought some of those plastic chocks from Walmart some time ago. Accidently backed up over them and crushed them. Bought some solid rubber from Harbor Freight. Much better purchase. See, told you that you would get lots of great suggestions as there are many campers on this forum with tons of diverse experience. I personally have purchased virtually EVERY piece of junk sold as a camper accessory and most lies somewhere in the heap of junk in a cabinet or storage bin.
