Welcome abord from a fellow Washingtonian (Anacortes). We have only seen three other rigs like ours in two seasons out there. Our rig is a used one (we're the second owners) and, so far, I don't see any issues that would require factory intervention.
We had a water leak over the winter through the Living room slide ceiling that was due to a rotted-out topper. I'm about 60% through the process of eliminating all the wood that got moldy by buolding replacement cabinets.
As I've posted elsewhere, I was amazed when I removed the old cabinets. Despite the slide ceiling having three steel tube structural members running the full length of the slide, the cabinets were held in place by 3/4" self-tapping screws that went through a sheet of 1/8" lauan mahogany door-skin materisl into the block styrofoam insulation. All but two of the twelve screws holding the cabinets to the ceiling wouldn't actually unscrew. They were in oversize holes caused by rotting of the plywood. It's amazing the whole thing didn't come crashing down on us last season.
The first replacement cabinet is installed and I'm working on the seond one. It would take an FR tech to spot the difference, I think. The new box is tied into those steel tubes and it's not going anywhere! Second cabinet is under construction - should be finished and intsalled in a week or so.
