Repairs, diagnostics, and installs

Heavily corroded RV house battery terminals and cable ends inside an open battery compartment during a mobile inspection in Northern Arizona — Electrical & Batteries
Years of corrosion building on the house battery bank. Found during a no-power call and cleaned back to bare metal.

Technician using a wrench on a corroded RV battery terminal beside a second house battery with green corrosion on the posts — Electrical & Batteries

A clean DC isolator and disconnect install with properly sized cable, fusing, and labeled busbar connections.

RV appliance control board with burned, melted plastic housing and scorched circuit traces removed for diagnosis — Appliances & Electronics

Bundle of colored 12V RV wiring with heat-shrink butt connectors and conduit being traced during electrical troubleshooting — Electrical & Batteries

RV 12V wiring harness repair with labeled gauge wire, lever connectors, and heat-shrink terminals inside a dark compartment — Electrical & Batteries
Harness repair with properly sized wire, sealed terminals, and connections that will survive vibration and weather.

Exterior RV power disconnect box and tankless water heater access door installed on a green-painted sidewall — Electrical & Batteries
Exterior power connection installed alongside a new tankless water heater door, sealed and flush to the sidewall.

Rooftop RV air conditioner opened up showing condenser coil, wiring harness plug, and control wiring during capacitor repair — Furnace, AC & HVAC
Rooftop air conditioner opened for wiring and capacitor work, with the coil cleared of pine debris.

RV furnace blower housing and flexible duct connection accessed from underneath the coach during a heating service call — Furnace, AC & HVAC
Furnace blower and duct connection reached from below. Rodent nesting and loose ducting show up here constantly.

RV furnace duct collar and mounting flange with wiring connections exposed during a ducting repair — Furnace, AC & HVAC
Duct collar resealed at the furnace flange so heat reaches the far end of the coach instead of the underbelly.

Newly installed black RV furnace exhaust elbow and pipe routed through insulation with wiring behind it — Furnace, AC & HVAC
New exhaust elbow routed and sealed. Combustion venting is the part of furnace work you never cut corners on.

Technician checking the dipstick on an RV onboard generator during an oil change and service — Generator Service
Oil service on an onboard generator. Regular changes are the cheapest generator insurance there is.

New brake assembly installed and the drum ready to go back on, with the spindle cleaned and repacked.

Worn RV trailer brake drum and hub pulled away from the backing plate for wear inspection under the coach — Brakes, Bearings & Axles
Drum and hub pulled for inspection. Wear patterns tell you whether the magnets and shoes are doing their job.

RV axle spindle and hub separated during a wheel bearing service call, showing the backing plate and brake hardware — Brakes, Bearings & Axles
Wheel bearing service on site. Repacking before a long descent is far cheaper than a roadside failure.
