Older DP issues and questions

What year, and a Magna or Affinity? All rubber should be inspected, particular the hydraulic hose, which powers the steering and engine cooling fans. Ours burst--no fun! We have an older coach than the one you are looking at, and we replaced all coolant lines two years ago as preventive maintenance. You should run all coach systems to see is they work properly--heaters, ACs etc. We have replaced all three roof ACs, and may have to replace one of them again. I know the factory is a long ways off for you, but they can do a full check-up. Butch Williams is an ex-Country Coach employee who works at a dealership in Florida. I am told he is very knowledgeable about Country Coaches, and he can do a complete coach check-out.
Some more info on your coach would be good!
