Mobile RV Repair in San Marcos, CA
Certified mobile RV repair in San Marcos, San Elijo Hills, Lake San Marcos and along the 78. We come to your driveway or storage lot.
RV service along the 78 corridor
San Marcos sits right on the 78, a straight shot from our Oceanside shop, so it’s one of the easiest areas for us to cover. A lot of North County RV owners keep their rigs in storage lots along the 78 corridor, and that’s where a big share of our San Marcos work happens. We meet you at the lot, fix the problem there and you never have to hitch up.
It’s also noticeably warmer here than on the coast. When summer heat sets in, AC units that were fine in spring start struggling, and refrigerators work harder to keep up. Those are the calls we get most from San Marcos in the summer, especially before holiday trips.
In neighborhoods like San Elijo Hills and around Lake San Marcos, HOAs often limit how long an RV can sit at the house, so owners tend to schedule service for the day it comes home to load up. Tell us your window and we’ll work with it.

What our customers say
“We were having some issues with our 5th wheel, I reached out to Josh and he got back to me so fast my RV was repaired and ready to go same day! Unbelievable service!”
Cynthia Haro, Google review“Josh Holt was only 1 of 2 repair people in North San Diego county that I could find to repair a cable slide out on my 5th wheel. Josh scheduled my repair appointment in one week. The other large RV retailer that said they could repair the slide could not even get me in for 6 weeks. Josh came on time and completed the slide repair the same day.”
