Would like to know if anyone in the Richmond, VA. area has had their gas engine coach serviced for oil changes, transmission tune-up, engine tune-ups and etc.? And if so where do you take it? I prefer NOT taking it to an RV dealership as they rip you off and charge RV prices! I had a bad experience with one service shop in Ashland, and learned an expensive lesson, so PLEASE no RV dealerships. Many thanks for any info.
