That's why the 40-foot and longer coaches are so much more stable. They are built on a long wheelbase chassis and have a relatively short overhang behind the rear axle, especially if they have a tag axle.
well said and to the topic!

Yes, Sometimes very little, sometimes if there is a crosswind and the semi passes at 80 MPH we get a push. I noticed the last time we were in any kind of wind the semi's were fighting it also.

DO not let being pushed by a semi deter you from getting what you want

Not quite correct . A track bar (Panhard Bar) is used to reduce the side-to-side movement of a solid axle mounted on leaf springs or air bags. Older GM gas chassis had independent front suspension, so a track bar isn't needed except on the rear axle. Later Workhorse gas chassis, and Ford gas chassis, have solid front axles so can use a front track bar along with one at the rear. I suspect Diesel pusher chassis with air bags and solid axles front and rear already have track bars. Again, independent suspension doesn't need a track bar.
