Here are the following problems we have had. One of the fuel gages quit working, the dump tank valves are hard to get to, the tank monitor lights/levels didn't work from the beginning, have been looking for a 12 volt electrical problem for nearly a month, one of the under sink vent caps was stuck open with some kind of goop inside, so the smell from the dump tank came up into the bathroom, (took us over a year to find that one), have asked for a wiring schematic, (rumor has it they don't even have one for the assembly line), a wiring harness as thick as your wrist wasn't installed correctly in one of the slides and consequently after about the first few months of use, pushed out one of the wooden panels hiding it. One of the holding tanks was labled "grey" when in fact it was a black tank, with no back flushing capibility yet.
Kinda hard to return it to the dealer everytime something happens when the dealer is 1500 miles away and we're full timers. Also it makes it difficult when some dealers won't honor FR's warranty. I could go on but I hope you get the idea.
