Every review earned. Every job done right.
"Josh is the real deal. We have used him for all kinds of repairs over the past two years and there is no job he cannot handle. His knowledge of RV components is genuinely impressive."
"Camping in Sedona, water heater kept shutting off. Josh was already at the campground, stopped by, diagnosed it on the spot, and didn't charge us a thing. What a genuinely good guy."
"Water pump died the night before we had to leave. Called at 6am, on the schedule by 11:30, met us in a parking lot, fixed it, and we made it to the Grand Canyon ahead of the weather."
"Josh installed an air brake system on my 2000 Monaco Dynasty. Everything looks like it came straight from the factory. Would not hesitate to have him do any other work on my RV."
"Professional but felt like family. Found it, fixed it, and even caught a second problem I didn't know I had. He has my business for as long as he wants it."
"Had an issue with my water heater and Josh walked me through the troubleshooting over the phone to save me a service call. Not many people would do that. First call for any future repair."
