Starting the planning process for building a garage for my Greyhawk motorhome. It's been good to me and I want to get it out of the weather. I want to combine the garage with an addition for ATV, UTV, mower and supplies area. Third area would be a finished room with possible old wood stove. More of the man cave theme without the TV and fridge. Looking for suggestions regarding design ( dimensions, concrete flooring, doors, windows, skylights, etc) and the usual if I had known now when I built it I would have done this differently thoughts.
