I travel out West all through the Great Plains and we are accustomed to the high winds. I installed four corner air bags that I pump up to about 80PSI on windy days. This stabilizes the box on the chassis. I do not adjust my tire air pressure and I find that it makes no difference. It is the leaning of the box on the chassis that causes the problem. My air bags are controlled by an on board 12 volt compressor that I can control from the dash to increase pressure in high winds and lower the pressure after the winds have passed.
