Congratulations on your purchase!
I have always characterized our camper as an Amish woman. Kinda plain, but hard working and dead reliable. There isn't a lot of fluff to these units, but they seem to be put together well. We never used our warranty for anything.
We bought ours new in 2013 and have used it almost continuously since then. Even when we aren't on the road, I have power, water and sewer connected at home and am in and out all the time. Just before the first freeze of the year, I'll go ahead and remove the water line and winterize the camper, leaving power connected with an electric space heater inside. I'll often go out to the camper to watch t.v. when we have conflicting show schedules.
Things to be aware of:
I didn't even try to use the electric part of the water heater until the end of the second year, since the auto light is so easy. Turns out my element is blown (probably during PDI). It's a pain to change, so I haven't really gotten around to it yet. I might get to it one day.
All the water lines are PEX, which is good, but all the connectors are plastic. The crimp rings are the kind that compress on one side (not my favorites). At some point I intend to replace the plastic fittings with metal and use proper crimp rings.
We had our first water leak several months ago. We were in Charleston, SC in torrential rains and the gasket around the slide leaked. I had never paid much attention to that gasket, but have since noticed that sometimes it doesn't completely roll over. It "flips" from one side to the other as the slide moves in or out like a wiper or squeegee.
There is a pick up tube under the sink area. Use a square head driver to remove four screws to take out the dividing wall under there to get access to the back of the water heater, the bypass valves, pump, and pick up tube. Sadly, the fresh water tank is under the floor, but you can see the fill tube to get an idea of where it is located. The fresh water tank also has a low point drain under the camper. There are also low point drains for the hot water and cold water lines up near the black and grey tank drain valves.
You have the older Deluxe model, which means you have the black tank flush which is mounted on the curbside near the bathroom door. These have a poor reputation and were discontinued in mid year production when the "Deluxe" moniker was dropped. Just be sure to get it completely drained and maybe figure out a way to get some pink stuff in the line (it's pretty long) when you winterize. I'd say that's the single toughest item you have to take care of.
I inject wheel bearing grease prior to every trip. Just make sure you inject it slowly while spinning the wheel and it'll work just fine.
I can't think of anything else, but if you do, feel free to give me a holler!
