The ShelterLogic Garage-in-a-Box 13 x 20 ft Gray Peak Style is the largest Garage-in-a-Box yet. 40% of vehicles on the road today are SUVs or full size trucks. We built this garage just for them with a full 8 ft of door clearance. Alpine frame with reinforced roof structure adds more volume and overall strength to the garage. The advanced engineered polyethylene cover is waterproof UV-treated inside and out resulting in a fabric cover that withstands the elements. Ratchet-Tite cover tensioning system ensures a tight cover and connection to shelter frame. Quality ratchet and web strap components keep cover tight and neat looking.
