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

McBrides RV Service in Chino, CA, is my go to shop when I need repairs that might take more than a day. Full time RV’ers know the hardship if you have to move out while your RV is in the shop. McBrides offers full timers sites for us who live full time in our rigs. Yep, we spend the night at their facility. The service is great, the people are friendly and they know how to fix RV’s. I highly recommend McBrides RV Service for whatever your needs are. - 9/26/2025
