Yet another approach. I've seen a few commercially built wagons made this way, so I thought I'd try it on one of mine. It costs less because there are no 4x4 cross members and 2x6's cost less per foot in shorter lengths than 16 foot lengths. I don't see why it wouldn't be just as strong. Now I have 32 2x6's supporting the outside edge instead of 5 or 6 4x4's.
