Mobile RV Repair in Leavenworth and Cashmere, WA

Mobile RV service in Leavenworth and Cashmere

Leavenworth sits where US-2 drops out of Tumwater Canyon on the east side of Stevens Pass, and Cashmere is about ten miles down the Wenatchee River toward Wenatchee. Between them are Peshastin and Dryden, orchards on both sides of the highway, and the side roads up the Icicle and the Chumstick toward Plain and Lake Wenatchee. The Bavarian village draws crowds all year, from summer river floaters and climbers to the holiday lights and Oktoberfest, and a lot of those visitors arrive in RVs.

The closest RV service bays are back over the pass or down in Wenatchee, and in season they book out. We come to the rig instead. If you searched for mobile RV repair near me from a campground in Leavenworth or Cashmere, we handle furnaces that won’t light, frozen or split water lines, generators, fridges, water heaters and dead batteries, plus power and connectivity work: lithium, solar and Victron systems, and weBoost and Peplink where the canyon walls block cell signal.

United Mobile RV LLC is dealership-trained, 11+ years: a Victron Energy Certified Installer, a weBoost Certified Installer/Reseller, a Dometic Professional and a Peplink Certified Associate.

• Leavenworth: in-town RV parks, driveways and storage, plus the Icicle Road campgrounds
• Peshastin and Dryden: orchard country along US-2 between Leavenworth and Cashmere
• Cashmere and Monitor: the lower valley toward Wenatchee, including the Expo Center and the county park

Leavenworth and Cashmere run on our Wenatchee valley route days. In winter, US-2 over Stevens Pass can close or need chains, so we confirm the day before.

RV parks and campgrounds around Leavenworth and Cashmere

We’re not affiliated with any of these parks. They’re places local RVers stay, and we’ll meet you at your site where the park allows outside technicians:

• Leavenworth/Pine Village KOA Holiday: on the Wenatchee River at 308 Zelt Strasse, open all year, with full-hookup pull-through and back-in sites and room for rigs up to 65 feet.
• Icicle River RV Resort: on Icicle Road about 3 miles from town, with 30- and 50-amp full-hookup sites along the river. It’s seasonal, so check dates before you plan a fall stay.
• Chelan County Expo Center RV park: in Cashmere, with 140 spaces that all have 50-amp electric, water and sewer. The park asks about RVs older than 20 years, so call the office first.
• Wenatchee River County Park: in Monitor between Cashmere and Wenatchee, with 49 RV sites, most of them full hookups with 20/30/50-amp service. It’s a seasonal park with no tent camping.

Holiday weekends, Oktoberfest and the winter lights season fill these parks early. If something fails mid-stay, call before you pack up; a lot of problems can be fixed at the site.

RV life around Leavenworth: real winters, hot summers and canyon roads

This is the east side of the Cascades, and winter is real. Leavenworth gets heavy snow and regular hard freezes, and the cold settles in the valley. That’s when we get calls for furnaces that won’t light, water lines that froze in an underbelly, split low-point drains and water pumps that cracked over a cold night. Winter visitors staying for the lights should have heat in the underbelly, a heated hose and a furnace that’s been checked.

Summers swing the other way. July and August are hot and dry in the valley, roof air conditioners work hard, and wildfire smoke some years means rigs sit closed up with the AC and fans running. Fire season can also bring burn bans and evacuations, so a rig that’s ready to move matters.

US-2 over Stevens Pass is a long climb from the west side and a long descent into Tumwater Canyon. Brakes, transmissions and cooling systems feel it, and a generator that ran fine at sea level may surge or stall at the pass.

Cell signal is decent in Leavenworth and Cashmere but drops out up the Icicle, in Tumwater Canyon and toward Plain. A weBoost booster or a Peplink router that can fail over to Starlink helps if you work from the rig.

RV repairs we do most around Leavenworth and Cashmere

The calls we get most from the upper Wenatchee valley:

• LP gas, furnace and water heater. Furnaces that click but won’t light, water heaters that fault out, regulators that freeze up or leak, and LP detectors past their date. We leak-test and pressure-check before we call anything fixed. A furnace that quits on a 10-degree night is the call we get most in winter, and we put it first. See LP gas.
• Winterizing and freeze damage. We winterize with a compressed-air blow-out, RV antifreeze where you want it, and a water heater bypass, and we fix the split fittings, cracked pump heads and leaking valves that a missed freeze leaves behind. Freeze damage is common here: split low-point drains, cracked pump housings and burst PEX in the underbelly. See plumbing and our winterization guide.
• Generator service and repair. We service and repair Onan, Generac and Kohler RV generators: oil, filters and plugs, plus surging, no-start and shut-down-under-load problems. Gas units that sit for months often surge because old fuel varnishes the carburetor; running the generator under load about once a month helps. Pass elevation and summer heat both make a weak generator show its problems. See generator service.
• Refrigerators. Absorption fridges that cool on propane but not electric (or the reverse), fridges that won’t light, cooling-unit failures, and residential fridges that shut off because the inverter or batteries can’t keep up. As a Dometic Professional we work on Dometic units every week, and we troubleshoot Norcold and residential fridges too. Absorption fridges struggle on hot valley afternoons, and that’s often a venting or cooling-unit issue. See our Dometic fridge guide and electrical and appliance repair.
• 12V and shore power faults. Crowded holiday weekends mean overloaded pedestals, burnt plugs and breakers that trip when the AC starts. We trace dead outlets, tripping GFCIs, burnt shore power plugs, converters that stopped charging and parasitic draws that flatten batteries in storage. See RV electrical.
• Victron, lithium and solar. As a Victron Energy Certified Installer we install and service MultiPlus inverter/chargers, SmartShunt monitors, Cerbo GX and VRM monitoring, DC-DC charging and solar. Lithium needs low-temperature charge protection here, and we set that up properly. See Victron systems.
• Starlink, Peplink and weBoost. Mounting and powering Starlink, Peplink routers that fail over between Starlink and cellular, and weBoost boosters for weak signal. Signal drops out up the Icicle and in the canyon; a booster or a failover router fixes most of it. See connectivity.

How a mobile visit works

1. Call, text or book online with the year, make and model, what the rig is doing, and where it’s parked around Leavenworth or Cashmere. Photos or a short video help.
2. We ask a few questions first. Some problems are a setting or a tripped breaker, and we’ll tell you if a remote session can sort it out without a trip.
3. If we need to come out, we set a day and a time window. Let the park office or storage facility know an outside technician is coming.
4. On site we test before we replace: meter readings, load tests, and thermal imaging where it helps. You get a plain explanation and a quote before any repair starts.
5. Most repairs are finished on the same visit. If a part has to be ordered, we tell you what and how long, then come back to finish.
