Eric -
My DFox just passed your house on the way back from Alaska yesterday. 11,000+ miles on the first trip, with one stop in LaGrande. I had some accessories installed and a gas leak fixed in the pump system, great factory service.
BUT - What I realized after leaving LaGrande, this being the first time on the road with this trailer, and a long one at that, was that the tanks, both grey and black, were installed dead level, with no support under the center of the tanks. The valve handles exited through holes in the frame that rubbed, one handle fell off on the road before Seattle, the other keeps opening the Black tank a bit, filling the sewage pipe with, well, you know, and the whole damn thing needs to be tipped 9" just to dump. Very, Very irritating. It's going to the dealer tomorrow to correct these problems, and replace a bunch of screws and trim that won't stay put.
The TV cabling was also wrong and one of the connectors was not installed, just shoved in the wall. The shower surround cracked and the plumbing needs some isolation treatment to quiet the pump down (common problem). I also didn't realize that the water heater is gas only, need to change that too.
A lot of trailers have 3500lb axles and light duty tires, the DFox has 8000lb axles and 'E' Rated tires, perfect for the places I go for hunting and work and I don't suspect that the overall construction will ever be a problem (of course I get s**t from my wife for buying new trailers every couple of years so we'll see). The frame and axles are quite sufficient and for a bumper towed 32' long trailer loaded to over 12,500 lbs it towed great. Only the plumbing irritates me.
