Mobile RV Repair in Airway Heights, WA

Mobile RV service on the West Plains

Airway Heights sits on the open West Plains between Spokane International Airport and Fairchild Air Force Base, with US-2 running straight through town. It’s a place where RVs come and go: military families heading to or from a PCS move, travelers staying at the resort park, and locals storing rigs on lots and acreage west of Spokane.

We bring the diagnostic tools and common parts to you, whether that’s a site at Northern Quest, a storage lot off US-2 or a driveway in Medical Lake. That covers the everyday fixes (generator surging, furnace not lighting, batteries dead after storage) and the bigger jobs like lithium, solar and Victron power systems.

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.

Where we work on the West Plains

• Airway Heights: along US-2, around the casino and resort, and the neighborhoods north and south of the highway
• Fairchild AFB area: off-base housing, storage lots and the roads around the base; on-base access depends on base rules
• Medical Lake and Four Lakes: lake homes, acreage and rigs stored south of the base
• Deep Creek, Nine Mile Falls and Reardan: farther out, scheduled when we’re working the West Plains
• Cheney: see our Cheney page

Heading west on US-2 toward Davenport, Wilbur and Coulee City? That’s our US-2 corridor page.

RV parks and campgrounds near Airway Heights

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:

• Northern Quest RV Resort: next to the Northern Quest resort in Airway Heights, with 67 RV sites including deluxe pull-throughs.
• Riverside State Park, Bowl and Pitcher: northeast of town on the Spokane River, with standard, partial and full-hookup sites for rigs up to 45 feet.
• Peaceful Pines RV Park & Campground: in Cheney, about 15 minutes south, with dry-camping to full-hookup sites for self-contained rigs.
• Fairchild AFB FamCamp: for authorized base patrons only. Check base rules before asking any outside technician to come on base.
• Storage lots along US-2: where a lot of West Plains rigs spend the off-season.

RV life on the West Plains: wind, cold and moving season

The West Plains are flat and open, and that means wind. Winter storms blow snow across US-2, wind chill drives cold deep into underbellies and wet bays, and an unheated rig in storage can freeze much faster than you’d expect. A proper winterization in October and a quick check after the first hard freeze save a lot of spring repairs.

Cold also catches batteries. Lead-acid batteries left partly charged can freeze, and lithium batteries must not be charged below freezing. A good BMS blocks charging when it’s too cold, which can look like a dead system on a January morning. We set up low-temperature protection, battery heat or a warmer location, and charger settings that match.

Summer is moving season around the base. A rig that sat for a year and is about to pull a family cross-country needs more than a wash: tires checked for age and pressure, brakes and breakaway switch tested, LP system leak-checked, and the generator run under load before it’s needed in a hot campground three states away.

Late summer often brings wildfire smoke to the Spokane area. Solar output drops, and people lean on generators and AC. We size systems with smoky weeks in mind.

RV repairs we do most around Airway Heights

The work we see most on the West Plains, with a short explanation of each:

• PCS and pre-trip inspections. Brakes, tires (including age codes), lights, hitch, breakaway switch, LP leak check, battery and charging test, and a generator run under load. If anything needs fixing before you leave, we quote it on the spot. Trip prep and safety check is a flat rate on our pricing page.
• 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. A generator that sat through a long deployment or a year in storage almost always needs fresh fuel, a carburetor cleaning or both before a big trip. See generator service.
• 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. Rigs parked on open lots out here take the full wind, so we pay extra attention to exposed lines, the water heater and the outside shower. See plumbing and our winterization guide.
• 12V and shore power faults. If you’re selling or buying a rig before a move, a full electrical check is worth it. Our pre-purchase inspection guide covers what we look at. 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.
• 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. An LP detector chirping or past its date is a common find on pre-trip checks; they have a service life and a date on the label. See LP gas.
• 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. For families who boondock on the way to a new base, a lithium bank with a MultiPlus and DC-DC charging makes long travel days a lot easier. 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. If you work from the road during a move, a Peplink router with Starlink and cellular failover keeps you online between towns. 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 in Airway Heights or on the West Plains. 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.
