Put up one of these in my yard this weekend seems to be well made.. Been at this for a while on putting something behind my shop to keep some stuff out of the weather.. Went with a 30x30x15 spent about $2800 delivered to my yard. It was the cheapest way to go everything thing else was double the price.. Only thing i don't like is the so called roll up doors in the front. Does anyone have any experience with these tents or what to look out for??
