My dad was a mechanic, so the bar is pretty high for me. We are in a 21′ RV and staying in Buellton. We could not pump the black water tank and we called Central Coast RV Service. They heard our concern and said their mobile mechanic could make a house call. In less than 30 minutes, Jerry arrived. This man knows exactly what he is doing and in no time he was able to diagnose (this is a real skill) the problem and then repair. Very professional, fair and honest pricing and we would not hesitate a second to use them again.
