I’ve had the pleasure of getting my RV serviced and repaired at McBrides several times, and each time I have had a great experience.

Labor rate is kinda high so I’d only use them for the stuff I couldn’t do myself. Overall good experience. Seemed like it was there longer than needed could’ve been waiting on parts not sure. I’d use them again. - 6/17/2026

I took my 1997 renovation project Fleetwood PaceArrow in for major mechanical service. I also paid for an hour of inspection on my failed slide out and got a great quote on the labor and parts for when I'm ready to invest in that repair next. I was a little weary initially that the service price on the phone when I called was told to me as around $500 range and then in person at drop-off the price was actually around $900 for the major service. But the girl who took my appointment over the phone had warned me that she was new and wasn't certain of the prices on anything. The service was great and I'm glad I chose to continue despite the wide price difference to what I was anticipating. Mike and Danny are stellar, and I know the place I'll be bringing my renovation back to with any repair needs in the future that I can't handle myself. The quotes for the slide out, and suggested drive train work, were both also very reasonable. - 6/04/2026

We had invisible brakes installed on our jeep to tow behind our coach. They worked extra hard to finish the job so we could take the jeep on vacation. Thank you McBride's RV. - 3/22/2026

Took my toy hauler for an estimate to fix slide, generator and transfer fuel pump. Parts needed to be ordered and since I had a trip coming up I picked up my trailer. When parts arrived took it back and it was completed in 2 days. Their staff is very friendly. What I really like about them is their scheduling. Gave me a date and time for both drop offs and pick ups. I was very satisfied with their work and highly recommend them. - 3/12/2026

Had a Tuson sway controller installed on our Apex Nano 186BH. Had scheduling problems on my end and they were very accommodating. Staff was very friendly and communicative from scheduling through pickup. Quick and smooth transaction. - 2/12/2026
