What Our Customers Are Saying About Us

Michael Meade

This is a busy shop...and it's busy because they are excellent. I use them for service on my diesel motorhome. Very knowledgeable and understand what they are about. If you have liquid springs or a diesel use this place!

Sam Rushia

Redmond Service is a very helpful and knowledgeable team of hard working people ready to dive into whatever problem you have rolling in. Their specialty in Diesel RVs, Freightliner, and Cummins in particular is amazing. Thank you Matt, Tegan, and James for all the help most recently!

Todd Goodman

Great having a Spartan repair service close by with Redmond Service Center. Matt does a great job communicating and listening and is honest and upfront with things. We took our 2020 Newmar Dutch Star 4369 in for engine/generator oil and filters, air filters, fuel filters, full inspection, tire replacements and slide controller repair to get ready for the season. We're going back for a CANbus diagnostic and TPMS pairing once that's repaired. Highly recommended.

Lance Gabert

Matt and team were great. Very transparent on recommendation and went above and beyond to ensure I got most out of my RV manufacturer warranties. Communication was outstanding. They are busy which is understandable based on the quality of service.

Jack Martone

"True professionals! From the guys on the floor to working directly with Matt the experience is always a pleasure. Have used Redmond many times and they never fail to address whatever the issue may be competently, quickly, and treat your vehicle as if it was their own."

Tony Brock-Fisher

Absolutely thrilled with the service at Redmond's! First time bringing my RV there for service, won't be the last. Sooo much better than Camper's Inn. I was able to get an appointment in a reasonable time frame, and they completed work on my RV within a few days instead of several weeks. Highly recommend!

Charles B.

Great place, very professional, was able to get me in and out during a busy season. Very grateful.

Jim Lemire

"Matt and his boys are truly amazing. They fixed so many problems with my f250 diesel in an impossible time frame and kept it reasonable..I would use Redmond Service Center for all my diesel repairs as should you .. thank you Matt."

Michael Kelley

Once they got my bus in for service it was a quick same day turnaround. It went in for what could be a moderately expensive issue and instead they came back with a simple inexpensive fix, just a couple hours of labor. They could have taken advantage of me but didn’t. These guys are HONEST! I will be back and will tell all my friends.

Raymond Peeples

Thank you for a great job!

Eric Ferrari

Matt and James saved us thousands of dollars on a generator replacement where one shop couldn't fix it, Redmond could! Amazing effort to turn around our RV quick. Really great staff with a bunch of hard working techs. You can tell Matt takes pride in the business and putting his name on everything they do. Will be back!
