Mobile RV Repair in San Marcos and Hays County

San Marcos sits on I-35 between Austin and San Antonio — a high-traffic corridor for RV travelers heading to the Hill Country, Corpus Christi, or South Texas. We see a steady pattern of service calls from RVs passing through on longer trips, owners stored in Hays County between travel seasons, and campground calls from Blanco River area parks and Canyon Lake-bound travelers who pull off in San Marcos when something needs attention before they continue.

Our technicians service RV air conditioning, electrical systems, plumbing and water heaters, roof repair and leak detection, and slide-out and leveling systems — all at your location in San Marcos. All work is backed by a 30-day no-fuss labor warranty.

We serve the full Hays County area including Wimberley, Kyle, Buda, and the communities along FM-150 and RR-12. Common parts for RV air conditioning, electrical systems, and plumbing are stocked on the service van, and most repair items complete in a single visit. Financing through Wisetack is available for larger repair or upgrade work.
