The Newmar Mountain Aire is the 4th Class A diesel pusher we have owned in 20 years. We have been extremely disappointed as we have Ben able to take a three trips. The electrical system seized and we could not open any doors, we had to wait months for a part. We were not able to take only one trip in 2024 to the Seattle area and another to Ouray, Colorado. We had to cancel our trip to Glacier National Park in July 2025 because of mechanical issues. We had a trip arranged to South Carolina in October 2025. We get ready to leave and the batteries would not charge. When I voiced my concerns to Newmar about the amounts of repairs , I was told they have no department for or solution for a RV that had continual repairs. We were on our own. So much for the $700, 000 + we paid for an RN that the shower was connected wrong, the closet door tracks were off, passenger seat problems along with electrical, battery, etc. Problems. Newmar patted themselves on the back because they answered our calls. The issue is, we should have never had to had these repairs to begin with. It is tantamount to buying.
