TODAY is a Great Day to visit our Store and order the parts you need for your truck!
16x28 is the size of the room upstairs in my garage and I can barely walk in there. You'll run out of space quick so I'll play devil's advocate. Bigger is better, ceiling height of 13' giving you the span to put a lift in there is ideal. Pour the pad fat enough to support a lift at least in the center. I wish my garage was at least twice the size, never enough! If you need concrete guys, builders etc I've got plenty of connections.
