Oh I know it. It was in the shop plan before I got sick. Should be fun to put up. I just hope they poured the concrete the way they were supposed to in the shop. I was in Kuwait when they did it. How thick do you need anyhow to bolt it down? I asked for 1' in a certain area but again I was not there for the pour of the floor. I do know they reinforced it with like a rebar 4x8 type of sheeting.
