Complete RV Services Offered

RV Repair
RV repair services focus on diagnosing and correcting mechanical, electrical, plumbing, and structural issues that affect overall RV performance. This includes everything from engine and drivetrain concerns to internal system failures that impact safety or usability. Repairs are completed through structured diagnostics to identify root causes rather than just surface symptoms.
RV Regular Scheduled Service and Safety Check
Scheduled service includes full-system inspections designed to keep RVs operating efficiently and safely over time. Safety checks cover critical systems such as brakes, electrical circuits, propane systems, and onboard appliances. This service helps identify early signs of wear before they become costly repairs.
RV Winterizing
Winterizing services prepare RV plumbing and internal systems for freezing temperatures and long-term storage. Water lines are drained, systems are protected with antifreeze where needed, and appliances are secured for inactivity. This process helps prevent freeze damage and system failure during cold-weather conditions.
RV Appliances and Components
Appliance and component services include repair and maintenance of RV refrigerators, HVAC systems, water heaters, and control modules. These systems rely on coordinated electrical, propane, and mechanical functions, making proper diagnostics essential for consistent performance and safety.
LP Appliance Specialist
LP appliance services focus on propane-powered systems such as furnaces, stoves, water heaters, and absorption refrigerators. These systems require safe fuel delivery, proper ignition, and regulated pressure. Service includes leak detection, burner inspection, and full propane system evaluation.
RV Refrigerators
Refrigerator service includes both absorption and compressor-based systems used in RVs. Diagnostics focus on cooling performance, power supply stability, and airflow efficiency. Repairs address issues such as weak cooling, ignition failure, or electrical inconsistencies.
RV Water Heaters
Water heater service covers both tank and tankless systems powered by propane, electricity, or dual sources. Service includes ignition testing, temperature regulation checks, and sediment-related performance issues. Proper function ensures consistent hot water availability for daily RV use.
RV Furnaces
Furnace services focus on propane heating systems used for interior temperature control. Diagnostics include ignition system checks, airflow evaluation, and burner performance testing. Repairs ensure safe and consistent heating during cold weather conditions.
Roof A/C Service
Roof-mounted air conditioning service includes compressor testing, refrigerant evaluation, airflow inspection, and electrical diagnostics. These systems are essential for maintaining comfort during high heat conditions and must operate efficiently under heavy load.
RV Generators
Generator service includes engine inspection, fuel system evaluation, voltage output testing, and load capacity assessment. RV generators provide independent power when shore power is unavailable, making them critical for off-grid travel.
Electrical (110V & 12V) Systems
Electrical service covers both high-voltage and low-voltage systems inside the RV. This includes batteries, converters, inverters, wiring, and distribution panels. Proper electrical function ensures safe operation of appliances, lighting, and onboard systems.
RV Plumbing
Plumbing services include freshwater system repair, wastewater management, pump diagnostics, and leak detection. These systems must maintain proper pressure and drainage to support essential RV living functions.
RV Awnings
Awning services include inspection, repair, and replacement of fabric, arms, and motorized components. Awnings provide exterior shade and protection but are vulnerable to wind damage, UV exposure, and mechanical wear.
Warranty Repairs
Warranty repair services involve manufacturer-approved diagnostics and repair procedures for covered RV systems. Work is documented and performed according to warranty guidelines to ensure compliance and claim approval.
RV Accessories
Accessory services include installation and integration of aftermarket and factory-compatible upgrades. These may include lighting systems, monitoring devices, storage solutions, and exterior enhancements that improve RV functionality.
Pre-Purchase Inspections
Pre-purchase inspections evaluate RV condition before buying. This includes full system testing across mechanical, electrical, plumbing, appliances, and structural components to identify hidden issues and maintenance needs.
RV Rain Leak Repair
Leak repair services focus on locating and sealing water intrusion points in roofs, windows, slide-outs, and exterior joints. Water leaks can cause significant structural and electrical damage if not addressed promptly.
Winterizing and Pre-Trip Service
This combined service prepares RVs for both storage and travel readiness. Winterizing protects systems from freezing damage, while pre-trip inspections ensure safe operation before hitting the road.
Why RV System Maintenance Matters in Arizona
Arizona’s climate creates unique challenges for RV systems. High temperatures in Mesa place heavy demand on cooling systems, seals, and electrical components. In Flagstaff, colder temperatures and elevation changes can affect engine performance, plumbing systems, and propane heating reliability.
Without proper maintenance, these environmental conditions can accelerate wear on RV systems and lead to unexpected breakdowns. Regular inspections and timely repairs help maintain system reliability across all travel conditions.
High Country RV
provides service solutions designed specifically for these regional demands, helping RV owners maintain confidence in their vehicles year-round.
Client's Testimonials
Bryon was excellent with communication, letting me know I can come in for service sooner than scheduled. He was able to redo my entire pvc sewage line from tank to valve. He was able to save me money by using undamaged parts. I was very happy with my service and it didn't take long at all. Bryon also told me of a fantastic spot to park the RV in the forest which was much appreciated (I am out there now 😊)
I totally recommend High Country RV. Thank you again!

We had a problem with our invertor (although we did not know that was the problem at the time) and contacted Bryon. He worked within our schedule and came out the next day to determine the problem and was able to order the part and install it as soon as it came in. We were able to keep our trip schedule. He was great to work with and we would recommend him to anyone!! Always nice to deal with good honest people.
