Welcome from Wisconsin and congrats on your new camper. Under the Library tab above there is a PDI (Pre Delivery Inspection) checklist that you can download and take with you. Or you can do a google search for one. Basically check out every system including fridge, water heater, furnace, stove/oven, AC, awning, TV, stereo, etc. Take a nightlight with you and check every outlet inside and out. Try every light. Check all exterior caulking. Do the windows open easily? Check screens for holes/tears. Check all fabric on sofa/chairs/bedspread for tears. Hopefully your dealer will have it hooked up to water so check for any leaks, look under sinks and under the camper. Have them show you how to winterize and de-winterize. Take pictures or video the process. If something isn't right don't sign anything because once you do it could be hard to get it in to be repaired/fixed. Take your time as a good PDI could last for a couple hours. If there is anything you don't understand - ask them to repeat it. I know others will chime in with ideas too. Good luck and I hope all goes well.
