Trace RV water intrusion and limit hidden damage. Start with observations and accessible owner-level checks, not dismantling energized, pressurized or fuel-burning equipment.
Quick symptom-to-action table
| Symptom | Safe first checks | When to stop |
|---|---|---|
| Wet after rain | Inspect visible roof, windows and trim for damage from safe ground access | Soft roof or ceiling, extensive mould |
| Wet only when pump runs | Turn off pump and inspect accessible plumbing | Water near outlets or appliances |
| Condensation on windows | Improve ventilation and measure indoor humidity | Persistent damp insulation or staining |
Step-by-step diagnosis
- Make the area safe. Park securely, protect people from moving parts and turn off affected equipment if appropriate.
- Record the symptom. Note whether the fault happens on shore power, battery, generator, city water or tank supply, and whether temperature or weather affects it.
- Check the simple indicators. Read the control panel, error codes and owner's manual; verify accessible switches, supply levels and obvious obstructions.
- Change one variable at a time. Re-test only if safe and write down what changed; avoid repeated resets when protection devices trip.
- Escalate early. If the problem involves combustion, mains wiring, structural damage, brakes or persistent leaks, arrange qualified service.
Common scenarios
Wet after rain
First check: Inspect visible roof, windows and trim for damage from safe ground access.
Stop and get help if: Soft roof or ceiling, extensive mould.
Wet only when pump runs
First check: Turn off pump and inspect accessible plumbing.
Stop and get help if: Water near outlets or appliances.
Condensation on windows
First check: Improve ventilation and measure indoor humidity.
Stop and get help if: Persistent damp insulation or staining.
What not to do
- Document wet areas with photos and dry them promptly.
- Do not apply random sealants over unknown roof membrane materials.
Canadian travel considerations
Cold weather can affect batteries, plumbing, seals and propane performance; heat waves place additional demand on cooling systems. Before remote travel, confirm your roadside assistance coverage, carry a charged phone and backup communication method where cellular coverage is limited, and check current weather and road advisories. Record the model and serial number of the affected appliance to help a Canadian mobile RV technician identify parts.

Locating leaks
Look at roof seams, window seals, plumbing and fittings, and trace stains back to the source. Repair quickly to prevent rot.
