I have a 2001 winnabego Itasca Sunrise, my problem is when I set the emergency brake and when in park, on a downhill slope it moves forward, what could be the problem?
If it is a Chevy chassis it probably has the auto park system. Most large Class A MH's don't have a parking pall in the transmission or emergency brakes like a car or truck. If you post your chassis you will get help as to how to adjust the system.
