RV Repair & Service for Rolla, MO

Rolla sits right in the middle of the I-44 corridor between Springfield and St. Louis — one of the most heavily traveled RV routes in Missouri. Home to Missouri S&T and surrounded by Ozark forests, Rolla is both a destination and a pass-through for thousands of RVers every season. The Mark Twain National Forest is in your backyard, float trip outfitters line the roads, and campgrounds dot every county road.

3R RV Service Center is just 70 minutes east of Rolla on I-44 in Union, MO. When something breaks down on the I-44 corridor — and it does, constantly — we're the factory-authorized shop that can handle it properly. Not a patch, not a temporary fix, but a real repair done by RVTI Level 4 Master Certified technicians.

The I-44 Breakdown Corridor

We call the stretch between Rolla and St. Louis the "breakdown corridor" because we get calls from it every week. RVs overheat climbing grades. Generators quit after hours of running in the Ozark heat. Slides jam from uneven campground surfaces. Roof leaks appear after scraping tree branches at primitive campgrounds in the national forest. If it can go wrong on I-44, we've fixed it.
