WOW, who thinks of this stuff. Awesome portable storage, for a M/C. Don't have to be, a mechanical engineer, to figure it out. Must find a way, to secure it, to the ground. It Will blow away. I mounted mine, on a sheet of 5/8 " Plywood, with a 4 X 4 frame. My bike sits on the plywood, with the 4 X 4's around it. The 4 X 4's added 3 1/2" to the height of the shelter. I can almost stand up, inside of it.
