We have a 2004 Newmar diesel that we have had for 3-1/2 years. Love the space and the driving comfort. However, we have put more money into it than we thought we would. Not for major repairs because there have not been any. But there seems to be always little stuff to do and the preventative maintenance is higher than we thought it would be. We follow all the Freightliner and Cat maintenance schedules.
Then we had the issue with paint checking and brought it back to Newmar for a sidewall replacement and repaint. The fact that we spent the money on the sidewall replacement and repaint also tells you how much we like the coach and for us, it was worth it to have it done and keep this coach. We plan to have this coach for many more years and many more miles.
