If you don't feel comfortable driving, don't. We travel a lot in the Great Plains and are used to heavy winds. I found that the toad helps to stabilize the coach in the high winds. I air up everything to stiffen the ride and this works out well for me, but I have thousands of miles of driving in high winds.
Again, if YOU don't feel comfortable, just wait it out. Usually very early in the morning, before the sun comes up, is best to get on the roads as the winds are still fairly light for a few hours after sunrise.
