Yes, the enclosed tanks are mainly to allow use into marginal weather months. Be aware also in shopping for an RV, pay attention to weights.
Some RV manufacturers build so close to the capacity of the vehicle you go over the rating as soon as you add people, food, living necessities and water. If you plan to tow a car for use when you get somewhere, check the hitch capacity and towing capacity of the vehicle. This information is usually found in a closet or cabinet, don't go by the dealer's say so.
Good luck and hope to see you down the road.
