Finally got our 99 Dutchmen Classic 30RL set up in a nice RV park. Cedars RV in Ferndale, WA. The only real issue I had was getting the Atwood water heater going. The sales person at the dealership didn't say anything about water bypass valves, but a call to their service department helped me get those valves turned the right way --- all three horizontal.
Then the pilot wouldn't light so I called a mobile service guy who was very helpful and suggested air in the gas lines since the trailer had been unused for a quite a while. He also said turn the blue gas control knob counterclockwise to pilot and then another 1/8 inch or so against spring tension and hold it there while the electronic spark keeps firing. Eventually the pilot got actual propane and lit.
Also discovered that there is an electric heater with a switch under the oven on the water heater tank if I ever want to heat water with electricity instead. Actually the service guy said you could heat with both at the same time.
The trailer and the site have 30-amp service, so..... running a space heater and the coffee pot trips the interior breaker. Not a big deal and the propane furnace works fine. I can put on a sweatshirt, but got to have my java.
The trailer is really very level, -- checked the bottom shelf of the freezer section. I did notice a mud dauber wasp nest in the refrigerator propane burner section --- cleaned that out but don't plan to run it on LPG anytime soon since we have full hookups here.
At first the water taps produced that red RV antifreeze stuff but that cleared up. Probably should have run more water through before the first pot of coffee though. On the 2nd day it was much better.
