On the way home from WRV factory I pulled over on the side of the road (still on the black top). I shifted into neutral & applied the parking brake and went to the back of the coach. After a few minutes the coach started to rill to the right and went down an embankment. I still don't know why the coach did not rill over on its side. All I received was a few bruises. It took two tow-trucks to pull the coach out. The coach received a few minor cosmetic damages. I checked the parking brake with the tow-truck drivers and it would not hold. I am taking the coach to Cummins West on Tuesday to inspect & repair the parking brake.
Please check your Parking Brake, I was very fortunate, it could have been fatal.
