Lynx blocks work. We carry 3 sets of them and a few pieces of wood. The lynx blocks are lighter and won't add weight if they get wet. Plus if you get dirt or mud on the blocks, you can rinse them off. Rinse the wood and it stays wet for a while. Since it's a trailer, I assume you must be pulling with a truck? You can get away better and easier throwing 5' sections of wood in the back of the truck. We are limited on space in our Class C and don't want to have to dig out the wood pieces of that size. Like I said, we do carry a few pieces with us, but they are no more than about 18"-24" in width.
