Several years ago we were traveling east on I70 through Kansas and encountered an extremely powerful wind coming from the north-east. My first clue was when I noticed my fuel gauge seemed to be going down faster than usual. I stopped to refuel and noticed a bunch of motor homes and pull trailers parked all over the place. When I was done refueling a gentleman came up to me and asked me how I was managing to drive in the wind and pointed to all the MHs parked there, explaining they were all waiting the wind out. I guess I hadn't really noticed it was windy, we continued on with the only casualties being 7MPG on that stretch vs the 12MPG we had been getting and a window vent visor that was ripped in half by the wind. When pulling our 5th wheel, I have to constantly check to make sure it's behind me.
