That’s comforting, not sure how well they’d do though for sure I’d get a hard shell!Good Question!
The guy in the Land Cruiser has an iKamper and said he has survived 50mph wind gusts in the San Rafael Swell. The RTT guys said if it gets really bad, you just turn the vehicle so the hard shell takes the direct hit of the wind. My tents would have survived fine if I had some way to stake them down. The orange tent in the picture was already pre-damaged from a Moab trip in May. I stayed in Sand Flats Rec area and Utah is one giant rock with 3" of sand on the top, no place to stake a tent. The dumb thing collapsed on me when the wind blew, bent up the poles nice, Big Agnes support is terrible.
I've had tents in 40 mph gusts and as long as they're staked out properly, I've had excellent success.
I towed a camper to Anza Borrego in some pretty horrendous winds, not sure how strong, but I drove past some guys in a regular tent who must’ve felt like you did, it looked like it a flag on somebody’s car going down the highway. I don’t know how you could sleep a single minute like that.
