Three new issues on my 39R12 came up during our last trip. The recently installed slide toppers shed parts when I opened the slides, and the rear awning, which I have only opened once, would not retract electrically. Motor hums and blows fuse. Had to manually retract with a power screw driver and 7/16 nut driver. And someone liberated my 5th wheel lube plate, which reminded me to examine my pin box rating, which is plainly marked "18,000 lb. max, do not exceed." As the max gross is 21,000, and my actual weight when loaded with both trikes and full gear (no water, and only minimal fuel in the genny and toy tanks is 19,300, I'll be talking to the dealer about that detail when I once again return it Friday.
All in all, the problems have been minimal, and taken care of by the dealership quickly. We love our unit, and the good has far outweighed the bad!
