I had a 39 ft. National Tradewinds and twice I had the pleasure of driving it in Misspuri and Oklahoma in winds that were blowing semis over and I could see my tow whippin back and forth behind me but felt little affects, that was a diesel, then I picked up my 40 ft. Newmar Canyon Star and headed across the desert with 43 MPH cross wind gusts, Stopped at a roadside rest and had lunch with the coach rocking slightly but it handled great. Just slow down and expect the worse and wait for that next gust, if it's too bad get off the road.
