Man this thing took me 4 days to paint. I knew if I waited until later I would never do it. two coats, primer the whole thing. I have my boat and cars in there now. I bought a few cabinet from Lowes and will make some of my own too.
The floor drains are a nice feature. It is very easy to put in now. How high did you pitch the roof? I used a sissor truss with a 6x12 and 3x12 inside. Over the x40ft it added 5ft inside.
