RV systems — how your rig is organized
DecisionGrid treats an RV as interconnected systems: comfort (HVAC), power (shore, battery, solar, generator), water & waste, towing, and appliances. Pick the system first, then drill into symptoms, tests, and repairs.
Most “mystery” problems are easier when you know which subsystem owns the symptom. Low voltage at the pedestal affects HVAC and microwaves; water pump chatter is plumbing and 12V; a furnace that never tries to ignite is different from a furnace that lights then locks out.
Use the hubs below as section headquarters: each links to deeper indexes, buying guides, and step-by-step diagnostics already published on DecisionGrid.
Comfort: air conditioning, furnace, thermostats
Cooling, heating, airflow, and controls on the roof and inside the living space.
- RV HVAC hub Master index for roof AC, heat pumps, thermostats, capacitors, low voltage, and mini split upgrades.
- Heating & cooling systems (broad) Furnace + AC topics that sit outside the deep /rv/hvac cluster when needed.
- Furnace troubleshooting entry Ignition sequence, sail switch, and propane/electrical faults.
- RV AC troubleshooting flowchart hub Visual decision path across the most common roof AC failures.
Electrical: shore power, 12V, inverter, solar, generator
Power quality, distribution, grounding, and conversion between AC and DC.
- RV electrical systems hub Pedestal-to-panel mental model: breakers, converter, battery bank, and solar.
- Electrical troubleshooting index Structured entry when symptoms span outlets, GFCIs, and converter output.
- Generator sizing & shore power Match generator and cord capability to AC and converter loads.
- Test campground pedestal voltage Before you blame the AC, verify what the pedestal is actually delivering.
Water, plumbing, water heater, tanks
Fresh, gray, and black water; pressure; pumps; winterization.
Appliances, towing, slides, whole-rig view
Loads that interact with electrical and HVAC planning.
- Refrigerator (absorption / 120V / propane) Cooling failures that share shore power and level issues.
- Microwave & kitchen AC loads Often tied to inverter, GFCI, or pedestal voltage sag.
- Towing & road gear TPMS, hitches, and backup cameras.
- Slide-outs Motor, hydraulic, and electrical faults for room extensions.
- Master RV troubleshooting guide Cross-system symptom index and publication update log.
