Wild winds wallop western Wisconsin
As stated in another thread, semi's that get tipped over from wind are usually empty. Which was the case here in this news story.
Even tho they might be empty, the tractor and trailer empty, weigh a heck of a lot more then most RV's. Granted, most semi trailers have a lot more surface then most RV's. I still wouldn't want to be caught in a 100 mph wind out on the road with my rig, and I wouldn't want to be in it parked in a campground either.
