I looked at a TT this summer, that was blown over, rolled four times, in what they said was a 65 mph wind. It was a 2014 trailer, about 30' long. It was parked on the edge of town, on a sales lot. It sure looked to be cheaply built, and really came apart. No one was in it at the time.
I got caught in a storm with my previous FW, in a SP. The wife and I rode it out, but I am sure I felt the FW front raise slightly, a time or two. We were lucky, the wind hit the front straight on.
