40 x 64 x 14 priced here for about $15,000. Another $5000 labor if they build it. I wanted 14 foot height for expansion later. It will support pullin the RV out of the weather. I plan to put a lift on one end. This is with 3 overhead doors 12x12 and one entry door. I wanted to pull things in and out from the side so I don't have to move things every time I want what is behind it. Can't have enough space, and can't raise the roof later. You can add a loft to take advantage if the height too. Although you can take out a wall and put more trusses in, your truss width is as wide as it gets. 40 foot width is nice.
