Specialized Mobile RV Repair Serving the Madison, WI Area
United Mobile RV is a dealership-trained, Victron-certified mobile RV service — not a handyman operation. Madison sits along the I-90/I-94 corridor in southern Wisconsin, and United Mobile RV LLC brings certified diagnostic and repair work straight to your site, whether you’re passing through or based here.
Serving RVers Around Madison
Whether you’re parked at Lantern DeForest RV Resort, settled in for a stay at the Madison KOA, or camped at Capital Springs State Park just minutes from downtown, we come to your site. We also cover the surrounding corridor — Sun Prairie, Waunakee, and the Wisconsin state park system (Devil’s Lake, Peninsula, and Lake Kegonsa bookings run 11 months out for a reason).
What We See on the Road Here
Southern Wisconsin’s RV traffic runs heavy on travel trailers and fifth-wheels behind 3/4-ton and 1-ton pickups — weekend state park campers and shoulder-season travelers staging for a run south. The calls we get most in this corridor: trailer wiring and brake controller faults on tow rigs, battery and charging system diagnostics for boondocking at state parks with no hookups, and water heater or plumbing checks ahead of an early or late-season freeze.

Frequently Asked Questions
Do you come to RV parks and state park campgrounds, or just private driveways?
Both. Most of our Madison-area calls are at campgrounds like the KOA or Lantern DeForest — just send your site/lot number when you call.
Are you a licensed technician or a handyman service?
Our technician is dealership-trained and Victron-certified, with 11+ years of hands-on diagnostic and electrical experience — not a general handyman. Real diagnosis, real fix.
Can you do warranty-covered repair work?
Manufacturer warranty work depends on the brand and current authorization — call and we’ll tell you straight whether it applies to your rig.
Do you carry common parts in your service vehicle?
Yes — common fittings, fuses, connectors, and wear items are stocked. Anything brand-specific we’ll confirm before the call so there’s no wasted trip.
