I purchased this shed to store my HD Dyna Low Rider. The motorcycle fits if you ride in on an angle. Perfect size for what I needed it for.  Assembly took a better part of the day calling upon my wife periodically to hold panels during certain steps of assembly. I did utilize two 4x4 pressure treated wood posts in the front two corners (each side of front door) to stabilize the shed. I placed the shed on a wood foundation due to my driveway grade, from left to right. I also added an additional latch due to the wind being able to blow the doors open. Yes the side panels are then but they are very durable. so durable that the panel would pop out of the channel before breaking. Overall, I am happy with this purchase and would purchase this item again.  No maintenance need. Maybe just hit it with the hose when the pollen comes down.
