RV Repair & Service for Columbia, MO

Columbia is right in the heart of Missouri — home to Mizzou, a growing population, and a whole lot of RV owners who tailgate at Faurot Field, camp at Finger Lakes State Park, or use Columbia as a base for trips to the Lake of the Ozarks. If you own an RV in the Columbia area, you know the options for quality service are limited.

3R RV Service Center is about 1.5 hours southeast of Columbia in Union, MO. We're a family-owned, service-only RV shop with RVTI Level 4 Master Certified technicians. That means real expertise — not parts-swappers guessing at your problem until something sticks.

Why Columbia RV Owners Come to Us

Columbia is a college town with a lot of things going for it, but specialized RV repair isn't one of them. Most shops in the area are general automotive or small dealership service departments that treat RV work as a side gig. At 3R RV, it's all we do — RV and horse trailer repair, rebuilds, and renovation. We're factory authorized for Newmar, Tiffin, and Keystone. We're Aqua-Hot, Oasis, HWH and Onan certified. We've been doing this since 2005.
