Harney Coach
I'm shopping for a good used Class A and was looking at a Harney RV. Are they well built, any major problems with them? General Feedback

We had a 1999 Harney Coach Renegade. I found that I had to replace about 4 of the single line water valves on the manifold every year. I replaced all by building an all copper manifold with brass valves. Problem fixed. Also, had to replace the main 12 volt power relay 3 times. Buy a spare and keep on hand for repair. While many auto part stores will have relays that look similar they are not continuous duty. Many Harneys had side wall delamination issues particularly on the slide out. Check for bulges on all the side walls. We found that the CAT 3126E engine to be very good. No repairs other normal maintenance. 10.6 - 10.8 mpg running 65-70 mph on interstate driving. Never went below 10 mpg even in the mountains.
