People need to realize that RV's are a totaly different breed compared to cars. In a car dealership different models may take the same part and so dealerships carry many of the same part on hand.
In RV parts two identical units will have different parts. The wiring could be run different depending on who wired it! It is on average a of a week to have your RV down. Better hope you dont have an accident because I have seen up to 5 weeks just to get a compartment door!!
Your best bet is to watch over your unit and when you notice something odd is to get in to your dealer, have the tech look over your RV and get the parts ordered and bring it back in ad soon as the parts are in so you are down for a minimum amount if time. Also take care of your RV and do the annual maintenance so you dint have major breakdowns.
Reason of review: Damaged or defective.
