RV Tips - Common Issues

RV ownership offers incredible freedom, but it also comes with a unique set of maintenance challenges. Being prepared for common issues can save a trip from disaster and ensure a smooth journey.

1. Battery and Electrical Problems

RV batteries are essential for running appliances and lights when not plugged into shore power. Issues can range from simple user error to more complex electrical faults.

Issue: Rapid Battery Drain

This often occurs due to appliances being left on, or a "phantom draw" from systems like propane detectors or stereos.

• Tip: Always switch off non-essential appliances when storing the RV or boondocking. Consider installing a battery disconnect switch on the house battery to completely stop all parasitic draws during storage.

Issue: Converter/Inverter Failure

The converter changes 120V AC shore power to 12V DC power to charge the battery and run DC devices. The inverter does the opposite, converting 12V DC battery power to 120V AC for household-style outlets.

• Tip: Regularly check the fuses and breakers on both units. If the converter is not charging the battery, ensure the shore power connection is secure and test the outlet with a known working appliance.

2. Plumbing and Water System Failures

The fresh, grey, and black water tanks are critical systems that require regular attention to prevent leaks and blockages.

Issue: Clogged Black Tank

This is a common and unpleasant issue, usually resulting from insufficient water use when flushing.

• Tip: Always use plenty of water with every flush. Use RV-safe toilet paper and chemicals. When dumping the tank, let it fill to at least two-thirds full before emptying. Flush the tank thoroughly using the integrated tank flush system or a wand.

Issue: Leaks in Water Lines

Vibrations and changes in temperature can loosen connections over time, leading to slow leaks, especially near the water pump or under sinks.

• Tip: Conduct a routine inspection of all visible plumbing lines and connections before and after each trip. Keep basic tools, like a wrench and sealant tape, on hand for quick fixes.

3. Appliance Maintenance

RV appliances, such as the refrigerator, water heater, and air conditioner, are subject to more vibration and movement than their residential counterparts.

Issue: Refrigerator Not Cooling

RV refrigerators often operate on LP gas or electric power, and are sensitive to being level.

• Tip: Ensure the RV is level for the absorption refrigerator to work correctly. Check the roof vent for obstructions (like bee nests). On gas mode, make sure the LP tank is full and the burner is clean.

Issue: Water Heater Pilot Light/Ignition Failure

If your water isn't heating, it's often an ignition issue, especially on older models.

• Tip: Clean the igniter/pilot light and thermocouple. Ensure you have bled the air out of the water lines after filling the tank. If using gas, ensure the gas supply is active and sufficient.

4. Structural and Exterior Concerns

The exterior of the RV, including the roof and slides, needs constant vigilance to prevent water intrusion.

Issue: Leaky Roof or Seams

Water damage is an RV owner's worst enemy, often starting with a small crack in the sealant.

• Tip: Inspect all roof and seam sealants at least twice a year. Use an approved RV self-leveling sealant to touch up or repair any cracks or voids immediately.

Issue: Slide-out Malfunction

Slide-outs can fail to retract or extend due to electrical, mechanical, or obstruction issues.

• Tip: Keep the slide mechanism and tracks clean and lubricated. Check the battery voltage before operating the slide, as low voltage can prevent proper operation. Consult the owner's manual for the manual override procedure.

System	Common Problem	Maintenance Tip
Electrical	Parasitic battery drain	Install a battery disconnect switch
Plumbing	Black tank clogs	Use ample water with every flush
Appliances	Refrigerator not cooling	Ensure RV is completely level
Exterior	Sealant cracking	Inspect and reseal roof and seams biannually
