Just look at my threads. Main thing to look for is the ends of the flex pipe when filling the fresh tank thst there are no holes in it feom a heat gun. Next make sure the all the fittings on the hot water heater are soldered ( mine wasnt on the output side, and flooded the basement). Make sure the two small windows on the rear side are installed properly and dont leak. Check all the 75 ohm cable hook ups. Some were on wrong connections, some were not hooked ip at all. Extend the awning and look at the wire covers on the front leg that it is secured. Try to pull the bottom plug and of it comes off you will have to silicon in back in, otherwise you will loose them. Be careful of the unfinished cdx stran board on the bed (the splinters are huge). Check the light switches in the slides. Last thing i can think of off hand, if you use the clothes bar in the front, you need to devise a support rod. It will pull out.
I have to say, i make several trips back the dealer, whom fixed everything. Last summer we went from Illinois to North Carolina and back, then illinois to washington (seattle) and back, with no problems. Im planning on a Coos Bay Ore trip this year. Get the bugs out and you will enjoy it.
