- CBChris ButtonJan 19, 20261.0My motorhome was here over a week and they couldn’t tell me why it wouldn’t start. They wanted to replace my computer. Javier the service adviser had lots of BS to tell me, including that they checked my fuel delivery, none of it true. Finally the service mgr Danny stepped in before I blew my top but it still wasn’t running. I towed it home with my pickup. It took a mobile diesel mechanic 1.5 hours and I was running…. After he plugged the computer back in they left unplugged It was the fuel module! I was left with several big greasy footprints on my carpet though to remember them by…. I’m sure this is a good shop just don’t deal with Javier, So many lies!
- RHRobert HamiltonNov 30, 20251.0I have nothing nice or professional to say about this company or the people. I had diesel in my oil, so I had them diagnose. They told me all 6 were leaking. When I dropped it off I told them I wanted to know what injectors were in there and what cam I had. I had multiple conversations over the phone and all they could say is they were S50&S60 injectors. I explained I wanted the four digit number to knkw if they were 7014s or 7650 all they said was S50&S60 injectors.
