Congrats on the new camper. Hope you get a lot of enjoyment and relaxation out of it.
As for parts, http://www.pplmotorhomes.com/
seem to carry a large assortment. I haven't purchased from them, but others claim good service. http://www.campingworld.com/
carries a lot of stuff, and you may have one close by. Where are you in North Carolina, as Winston has some big dealers. Also take a short trip before Memorial day week-end, get familiar with it, and how everything operates, even you have had a camper, this one will be different. Good Luck.
