“We needed a mobile RV mechanic for an issue we were having with our coach. 911 RV Repair came to the rescue. Although they weren’t actually able to diagnose our issue because we were locked out of our storage garage, 911 RV showed patience and understanding after driving quite a distance to our RV location. We were so impressed with their professionalism in this most uncomfortable situation. We would like to recommend this company based solely on their professional attitudes as well as making us feel like the customer truly is put in first place. We will be having our coach towed to this business and will be writing another review after the work is completed!P.S. They fixed our coach in a short period that put us back on the road again. Amazing service and great service!!“

“Wife and I are very familiar with large diesel motorhomes having traveled around the US. We've never had better service than from Tim. He found and replaced a 6K diesel generator, replaced brakes and bearings and full fluid servicing. Also, he took the initiative to repair other smaller items he found. We can't say enough about the quality and thoroughness of his work. Hard to find today.We strongly recommend him for any of your diesel/RV repairs.Services: Oil change“
