High winds, especially cross winds, do make driving a lot more challenging/difficult. Continuous winds are bad enough but gusting winds are the worst.
In high winds, like we usually experience in the Great Plains, I pump my four corner air bags up to maximum air pressure and this makes it a little easier to maintain a straight course. We always found that getting on the road before the sun comes up gives us a little time to travel before the winds really start to pick up.
During the last hurricane I found out that our coach did not blow over in an 80 MPH wind with gusts approaching 100 MPH. At that time it was sitting on it's wheels, levelers up, and loaded close to how we usually travel. An empty coach, or semi trailer, are more likely to be blown over than one that is loaded.
Whenever you don't feel comfortable on the highway with the winds, stop for the day and just relax in an RV park or parking lot.
