About
My name is Ernie Koonce. I am the owner of Koonce’s Mobile RV Service. I am an RVTAA Certified RV Technician with a passion for camping and a love to assist others in making their dreams happen. In 2020, while researching the purchase of a new travel trailer, I learned servicing your RV was a challenge due to finding qualified technicians. At that time, I decided to learn everything there is to know about servicing my own rig. As I got into learning, I found that, by combining my passion for camping and my love for working on things, I could use these skills to help others with their needs. I then enrolled in the National RV training Academy to become a Certified RV Technician. I am currently certified in the following areas: • Air conditioners • Absorption Refrigerators • Furnaces • Water Heaters • Awnings • Slide outs • Stabilizer/Leveling Systems Along with providing repair services, I also provide preventative maintenance and optimization for your systems. This includes testing and cleaning AC units, furnaces, water heaters and checking vents for maximum air flow. It’s amazing what a little preventative maintenance can do to help things run smoothly. Let’s not forget Emergency rescue services. If you have a situation with your slides or stabilizers/levelers, give me a call. My goal will be to get you moving in the right direction, whether it’s moving forward with your vacation, or the assistance needed to get you on the road to your next destination.

Furnace Issue
We had our furnace go out during the really cold spell. After Ernie determined it was the motor, Grand Design shipped us the motor and Ernie fought the cold weather to install it for us. He was a wealth of information and super helpful. We definitely recommend his services.

Great work from a friendly RV tech
Ernie came yesterday for scheduled maintenance on my Brinkley. We took 18 trips with our Model Z this past season, and I wanted to have it ready to go next Spring. Ernie showed up when promised and dug in. He greased the wet bolts, inspected the brakes, repacked the bearings, and rotated the tires. While he was there, I asked him to take a look at the microwave inside as it was sagging a bit. The total cost was probably half what I would have paid at a dealer, and I didn't have to take it anywhere and leave it for weeks. Maybe most important: Ernie was a pleasure to work with. I plan to have him do service or repair work in the future.

Slide out
We had our trailer slide fail us. We called Ernie and he came to our trailer and helped us figure out what the issue was. He was able to order two new motors. He set aside the week to work on it so we could get it fixed and we were able to keep our camping plans as scheduled. Ernie was great to work with. We will definitely use him in the future!
