Our RV is a 2006 Newmar Mountain Aire 4304… Doris as we call her, because she is a strong southern lady. We purchased Doris from a dealer in Washington in April. The dealer purchased her in Texas. She has been well taken care of and has normal wear-and-tear. She has a large shower for an RV, a residential frig, and more storage then we need. She holds 150 gallons of diesel, 32 gallons of propane and 110 gallons of fresh water. She has a Cummins 400isl motor. And is built on a Spartan chassis.
