my roof is higher in the rear than the front, no way it would/could ever drain to the rear, however like Russ it drains into the gutter strip on which ever side it happens to run off to which seems to be the the side the door is on most of the time. the lil gutter strip does work well tho.
pete, in my opinion if their is one thing to have level it would be the frig.
I think it was mickey? that posted this.....
Any chance the rig has been parked on an un-level surface? Operation sounds like what may happen if not level while parked with frig running for some time. Some of the chromate in with the ammonia has gotten over heated and has partially crystallized and is partially blocking the flow of ammonia. Once chromate has crystallized, reduced cooling will happen on both power sources.
dont think it will happen quick but, shortin the life of it?
