Like jay-tee we purchased a 337rls (#481). We are currently on it's maiden voyage to OK (Winstar RV park) It is far enough away to get a good shake out but not too far that if something goes wrong we can get it back ok. We have been here for since 1-16 and will return to Arlington on 1-20. We are putting her through her paces as we plan on using it as retirees.
I was told by the dealer to make a list of the little thing s that need to be taken care of and on the return just go by and drop it off for the warranty stuff. I was told that there is always something. Welllll? Not really. I pure delight. Everything works and works like it was advertised. My comments reflect exactly what jaytee said. Wifey likes the kitchen, cabinets and counter space. I like how well it was constructed. Like most new things, there is a learning curve. We are learning all about it.
Here is a tip. When plugging in (50 amp) the male end has two tiny blue LED lights. BOTH lights should be on IF the power at the pole is good. We learned this after hooking up and the hot water heater AND microwave oven would not work. CHECK THOSE LITTLE BLUE LED LIGHTS. IF ONE IS NOT WORKING THAT MEANS ONE LEG OF THE POWER RECEPTACLE IS NOT WORKING AT THE POLE. You will save yourself a lot of tooth enamel and maybe a divorce if you keep that little tip in mind.
Beside that -- so far so great. We are having a great time with absolutely no, nada issues.
