We use two big totes that sit nicely on a platform plugged into the receiver on the back of our trailer. We mostly bring smaller pieces of wood, 2x4's, or kindling which doesn't weigh much. The center of gravity is pretty low so there's minimal movement and having the wood back there comes in very handy when parked at a campsite. If I do bring larger chunks, it' usually just a few and they ride in the back of the truck. We have a large family and our pickup has a canopy so everything ends up getting drug to the back tailgate area of the truck over the course of a weekend making it difficult to get things like wood out of the bed.
Just our experience.....:)
