Customer Reviews

Your business is very appreciated.

G and stars

Santin Truck repair has been a blessing for me in getting a qualified and certified Spartan chassis repair facility for my Newmar Essex coach. They helped me with road calls with issues. They have serviced my coach doing preventative maintenance. I have had paint touch work done and they did an excellent job. I have no issue recommending them.

Owning a motorhome gives you the freedom to explore the open road, but that freedom depends on keeping your vehicle in top condition. At Santin Auto & Truck Repair Center in San Antonio, TX, we specialize in motorhome repair and maintenance to help travelers avoid unexpected breakdowns and costly repairs. Routine maintenance not only protects your investment, it also ensures every trip is safe, smooth, and stress-free. Here’s three reasons to always keep up with your RV’s maintenance needs. Protect Mechanics Your motorhome’s engine and transmission work hard to move a heavy vehicle over long distances. Regular oil changes, fluid checks, and filter replacements are essential to prevent wear and overheating. Neglecting these services can lead to major engine or transmission failures that are expensive to fix and could leave you stranded far from home. At Santin Auto & Truck Repair Center, our technicians use advanced diagnostics to spot early signs of trouble and keep your motorhome’s powertrain running strong. Keep Your Vehicle Safe Because motorhomes are larger and heavier than passenger vehicles, their brakes and tires require special attention. Routine brake inspections help catch worn pads, damaged rotors, or low fluid levels before they affect stopping power. Likewise, checking tire pressure, alignment, and tread depth improves fuel efficiency and handling while reducing the risk of blowouts. Maintain Comfort From the AC and heating systems to electrical and hydraulic components, every part of your motorhome contributes to comfort and safety on the road. Regular inspections ensure everything from lighting to leveling jacks operates correctly. Preventive maintenance also helps preserve the value of your RV over time. Whether you’re preparing for a cross-country adventure or keeping your RV ready for weekend getaways, trust Santin Auto & Truck Repair Center for professional motorhome services in San Antonio. From routine RV maintenance to complex repairs, we do it all.. Call  210-890-5867  to schedule your next appointments or to learn more about our San Antonio motorhome maintenance services.
