I donated a factory built mini speed boat trailer for the build (I own a marine repair shop). Even though it was a 8" boat, the trailer was rated for 2000lbs. That trailer is built out of 3/16 2x3 box tube! Way overly built for such a small boat. It was easy for my son to square out the frame for this build. The trailer frame is 63" wide, so the camp trailer is going to be 63 and 3/8" wide by 8' long by 4" tall above the frame. It will have a 36" slide out on the back for the kitchen, This camp trailer will have 3/4" plywood sides and 1/4" roof. It will be pink in color!!!! I'm already three weekends into the build! Shame on me!
