I had a 1984 Sportscoach Pathfinder with a 454 cid Chevy engine on a P30 chassis. The only problem that I had experienced with it was roof leaks around the air conditioners which ended up causing its demise. When I purchased the unit, the unit was in excellent shape for a 20 year old vehicle, but after my work schedule changed the unit sat for about 5 years before I noticed the extensive water damage. The new owner got a good deal (free) on his fixer upper. The only problem chassis wise was the brakes were dragging after sitting for 5 years. The tires looked good but would need replacing after sitting 5 years in one spot. The amazing part was that he started it and drove off with a full tank of 5 year old gas with no Sta-bil. That old Chevy did not miss or sputter as it drove away.
