Any Class A MH, semi, bus, etc. is pushing a big wall of air. When you approached him, I assume on the left, it pushed his rear end to the right. Correspondingly his front went left, toward you. If you had watched him as you passed him you would have seen his front go back to the right due to the air pressure between the two vehicles. The less the passed coach weighs the more pronounced the effect. As you get into 39+ units the effect is almost non-existent.

I was in my tow car. The road was smooth. I watched for a while because I was interested in the Breeze. I have an old P-30 chassis and it never drove that bad even with worn front end parts.
