Welcome to the Wild and Wacky world of Class A owners.. You have made a good choice...Enjoy it in good health.
If you have not already done so check the owner's manuals (All 20 pounds of them) if you got them (ok so I exagarate a bit on the 20 pounds) if you did not, (or even if you did) I suggest you check out all the appliances, Televisons, Awning, Fridge, and what not, Go to the manufacturer's web pages and DOWNLAOD both the owner's and servie manuals if possible. This won't be possible for the "House" and may not be possible for the chassis, You will need to contact the makers for those.
A couple of books.. The RV book and the RV Owner's handbook are "Generic" owner's manuals you might want if you do not have the OEM ones as well.
Beyond that I will wait for questions to be ask, but these manuals give you, in many cases, the questions to ask.
Home is where I park it!
