Hey Norm,
If you need more than just engine service, I would strongly recommend Redlands RV/Truck service. I've had nothing but excellent service from them over the years with my Dynasty (now sold). They can adjust slides, engine service, etc.
I had them install the towing equipment on the new Honda, etc. All the work that they have done for me has been 100%. Do not go to Colton Truck in Colton....it's hit and miss....did not have good luck with them.
I know Redlands is about an 80 mile drive for you, but you will really like the professional people at Redlands RV service. They might even offer a mobile service as they did come to me in Palm Springs to change an air fitting.
