On a tip from a fellow camper, prior to a trip west, I installed a second anti sway set up on our 26' TT. It is a great help, but I did chicken out in southern Utah (Grand Staircase Escalante) when I drove north from Bryce Canyon to Torrey. The forecast was for high gusting winds. The (northbound) high road took us out on a fin that was several hundred feet down on either side of the road. Fortunately, we drove that route the day before, with just our truck, while searching for an acceptable spot for boondocking, so I knew what to expect. We decided on the road a few miles to the west that traversed the valley. Turned out to be a nice drive.
White knuckle driving is very tiring.
