I have an enclosed one I got from Northern Tool , I think it is 10 x 20. Reverend Bill has seen it : ) .The key is securing them to the ground, and putting them together square. I think mine was $179.It has a zippered roll up flap door on the front.I dug about 10- 12" diameter holes for the augers on all four corners and set them in concrete, then cabled the leg corners of the garage to the augers.The trick is having a nice level area and securing it down good.Mine gets pumeled with the wind alot. I will say though after it's third winter and sun, and wind it is starting to show some wear,after another year I might consider getting a new cover, hopeing they sell just the shell.It can be patched with regular tarp material , or so it says.I have one hole in it from a chunk of ice falling off the roof, catching in the wind and punctureing the top.I see alot of them in disrepair because of poor instalation.Not sure if I have a pic of mine.... Nice job Bill !!!
