RV's in a storm

We rode out 60 mph plus winds in our coach last fall while at a campground near Niagara Falls last fall. The neighbor's anemometer recorded 64 mph gusts. We were oriented with the rear of the coach pretty much facing into the wind, and while we did rock and roll a bit, we never felt like we were at any risk of blowing over. In your scenario, I think I would do the same thing, try to orient the rig so the wind is at the rear and ride it out. Keep in mind your RV is regularly exposed to 60 mph plus "winds" while driving down the road at Interstate speeds anyway. The only reason for facing the rear into the wind instead of the front, is to minimize any potential damage from flying debris.
