I had a Coleman Popup for many years. It was a great camper, easy to tow behind our minivan, and comfortable inside. No shower/toilet inside though. We were camping in Idaho along a lake when canyon winds started up. They were maybe 30 mph winds with a few gusts to 40 maybe. The camper survived but I was very nervous with all the noise, air infiltration, and stretching of the fabric. The winds only lasted a few minutes then it got quiet. I guess I would not want to go through another situation with winds even stronger or longer than those we experienced.
