I bought mine two years ago 25x12x11 14.5 ounce material. Set it up by myself no issues but I do own a tractor that helped -alot! This yr I added storage by using 2 x 6 x 12 PT across the last three supports and put a deck on them. I also used PT decking around the outside of the posts and boxed in the whole building making it even sturdier and keeping rodents out. I used 2x6x12 also across the rear door to make it far less likely for a breakin the front is visible to me. I added two tire racks on the back wall for my winter-summer tires. I also added LED lighting inside and a security camera. Snow just rolls off.......not even a slight concern. Wind no problems at all especially with the rear being tied together and the boxed in bottom.

I bought this garage to store a classic car and some equipment. It needed to be strong enough to take a CT winter storm... no problem there. It's been up for 3 years and so far it's taken anything nature throws at it. Great product!
