I have not driven a 45' MH, but have driven a 45' tour bus and there is a lot of difference between that, my 39' MH, the 40' Thomas school bus I normally drive at work and a 40' tour bus that I drive occasionally. Watch your turns and your rear end. I drove a 97 passenger Crown mid-engine and just about took out 4 cars turning a corner 'cuz of the major tail swing. That baby had tandem rear axles and a LOT of overhang.
