I'm the fat guy on the right.
I have to replace a couple of D rings on the raft and tweak some of the rigging, but I'm happy with how it turned out. The pipe is 1 1/4" EMT. I might end up redoing it with bigger pipe, but I think it's fine for now. The front box came from Home Depot and the rear box (which I already had) came from Lowes. They're injection molded, very sturdy, and cheap. They're sitting on the cross members. I'll strap them down for trips. The 120 quart cooler is on an NRS cooler mount. I put an NRS gear platform up front for bags, water jugs, etc. and will throw straps and a gear net over the pile. I ordered everything from Darren at Frontier Play. He was very helpful and the transaction went smoothly. He also saved me some green. Can't wait to get the D rings replaced and try 'er out. Shooting for President's Day weekend.
