My RV wouldn't start while it was parked at the mall. It was late, so I had to wait until the following day. My road service, SAM ROAD SERVICE, sent help. The mechanic tried to start it several times, troubleshooted the issue, and then informed me that he thought the starter needed to be replaced. His job was limited to starts and tires, but he recommended Randy's Mobile RV Service. My service provider called three other services, but they couldn't come - it was late Friday and they had too many calls ahead of me.

I asked them to call Randy's again, explaining that it was an emergency. Finally, Randy arrived and did some troubleshooting, discovering an electrical problem. It turned out that a new starter wasn't needed after all. I'm very happy with Randy and my road service, as I was finally able to get home to my animals. Thanks

Seriously, I've been using Randy's Mobile since 1999, I have a carpet cleaning business and no other shop has touched any of my vehicles or that of my friends and family. To say the technicians are the best is no stretch of the truth, detail oriented, every option is presented, Randy and JR are simply the best at what they do.

Randy and his team were awesome to work with. They were easy to work with and conducted the repairs quickly. Very good communication with what items could be handled under my warranty and what items I had to pay for directly. During pickup Randy provided fantastic insight into questions I had around trailer storage as well as outlining best practices for running the generator and battery lVery much appreciate the high quality work they did on the trailer and going the extra mile.

This is one of those overdue reviews. Randy and the crew were communicative, thorough, and go the extra mile to get things right. They were also super nice to me even though I showed up on the wrong day, with a fuel leak, no less. Even though my early arrival was quite the deviation from their well managed schedule, they kindly got the vehicle into a safe enough state that I could leave and come back on the right day.

At that point, they troubleshot a tricky brake system and an even trickier injector line system (turns out uhaul got "special" lines for their old e-350s). Turns out you can't order those. I was impressed because 1. they figured that out in the first place, and 2. they magically modified a standard e-350 line and made it work (!)

Thank you for being so kind, professional, and doing a great job. I don't know that any other shop would've been able to keep this thing safely running.
