It is coming together slowly. going to need a few more 2x4s and then start sheathing with plywood. I will most likely use a nice 1/2 or 3x4'' on the interior and then 1/4'' on the outside and stain it. Insulated also.
So are waterbed mattresses made after a certain date. My plans now are to use a 3x4'' bottom to prevent that from bowing out. Sheething the inside with 1/2'' or 3/4'' OSB and then a nice 1/4'' exterior and some stain.
Are you ably to afford real plywood instead of the Ian? Only reason I'm saying something is because I'm a licensed contractor. Osb will delaminate and become structurally unsound with moisture. Also, if structural soundness is a concern, I would get some Simpson hardware. It's available at home depot. Simply using a hurricane clip on the inside corner will do wonders. They cost 80 cents a piece, but you'd be surprised how well it works. In fact, I'm a contractor at the jersey shore, and hurricane clips are required by code for every single roof joist.
