Make sure EACH leg is bolted down and consider more that 2 bolts(screws) on each leg. I have 3 up now for 3 years and they are about wore out now. I had 2 blow into the condos next door before I got the anchor thing right. They can catch alot of air. Good thing about Costco's return policy. The door on the front helps keep some wind out of the "tent" and they are not so tight to worry about moisture build up! Happy tenting.
