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?
I'm not sure any RV has an 'Emergency' brake these days. They're all called Parking Brake or similar. Just so they are protected against a law suit. And that acknowledges that the Parking Brake isn't as effective as the old emergency brake.
