I would suggest that you check into a campground with full hook ups. Staying outside the gate will not let you check very much. The water at the factory is really bad, heavy with iron. Just check the sink in the factory bathroom. I would not put it into my water tank. Unless you have a sewer hookup, you can not dump, check out the sani con system. Turn on the water heater, stove and microwave.
During the walk thru check every thing, open and close every door, drawer, window and roof vent. If you got the jacks, try them out. My last PC I forgot to check them and I drove all the way down to Indianalopis before I found them missing. I had to return the next day to get them. Take your bath towel rods and toilet paper holder with you and they will install them where ever you want them.
The Elkhart Campground is very close to the factory and a lot of stores, including Lowes and Mandlas (sp).
