I bought 2 of these. I needed storage for my cars since a fire made using the garages unusable. They are narrow, making getting in/out of the car a bit tight, OK, I'm 6'3" 250 lbs it's tight for me, but not impossible. They were easy to assemble took about an hour and a half. the directions are easy to follow and all of the parts are clearly marked. The poles connect and lock in the place by a spring button, the cover is thick. It has a bottom pipe through a sleeve in the shell, really a great feature, it allows you to make the skin tight and the skin is rated for 4 seasons. The pipes are shinny and a large od however they are not thick walled. we'll see how they handle snow. The top is peaked which should help keeping the snow from piling up on the cover. The length is a good size not too long taking up needed space and accommodates my cars without sticking out the end. It came with a piece to close one end, and the other end has a large zippered door. So far I don't plan or using the closed end, but might use the door facing the trailers. Where I'm been living since the house fire. At this point I recommend the unit. How it holds up to snow may change that. The 2 cars I'm putting in them are a 1997 Jeep Wrangler, and a 2017 Subaru Crosstrex. They do come in larger sizes but my limited space and the good price made it perfect for me.
