RV Repair & Service for Joplin, MO

Joplin sits at Missouri's southwest corner where I-44 meets the Kansas and Oklahoma borders — one of the busiest RV crossroads in the region. Whether you're a local RV owner, a traveler heading east on Route 66, or someone passing through on your way to the Ozarks, 3R RV Service Center in Union, MO is the factory-authorized shop worth knowing about on the I-44 corridor.

We're about 3.5 hours east of Joplin on I-44, and we serve customers from across southwest Missouri who've learned the hard way that not all RV shops are created equal. 3R RV is family-owned with RVTI Level 4 Master Certified technicians — the highest certification in the RV industry. We don't sell RVs. We fix them.

The I-44 / Route 66 Connection

I-44 follows the historic Route 66 corridor across Missouri, and it's one of the heaviest RV travel routes in the country. Joplin is where thousands of RVers enter Missouri every year heading east toward Springfield, the Ozarks, and St. Louis. When something goes wrong on that stretch — a generator quits outside Rolla, a roof starts leaking near Lebanon, or a slide-out jams in Springfield — 3R RV is the shop that can handle it right.
