Hello & Welcome Gary:
Congratulations on your purchase of the Alpine. For my $0.02 I would take the coach to Cummins make sure it is a coach care facility as the can work about anything.
I take the Alpine to a RV service center for the rest of the coach. You will find that the Alpine drives and stops like a car.
Just remember where the front goes the rear follows.
Hope to see you at an Alpine Coach Association (ACA) Rally or and Alpine Chapter Rally.
