Top Winter RV Issues

The top winter RV issues that we see at St. George Mobile RV Repair mostly center on freezing pipes (leading to bursts), battery drain, roof/seal failures (causing leaks from snow/ice/rain), tire pressure loss, and fuel gelling (especially diesel); pests, moisture buildup, and furnace/heating failures also plague RVs in cold weather.  Proper winterization is the key to preventing costly damage. 

Plumbing & Water Systems

• Frozen Pipes: Water expands when it freezes, cracking pipes and tanks, causing major damage.
• Condensation: Lack of ventilation leads to moisture, mold, and mildew. 

Electrical & Power

• Battery Drain: Cold weather significantly reduces battery performance and life, affecting furnace and lights.
• Power Loss: Running the furnace and other systems consumes more power, requiring careful monitoring. 

Exterior & Structure

• Roof & Seals: Snow and ice stress roofs, causing leaks around seams, vents, and skylights.
• Tire Issues: Cold causes pressure loss and can lead to sidewall cracking; use proper winter tires if driving.
• Pests: Rodents and bugs seek warm shelter, chewing wires and nesting inside. 

Engine & Fuel (For Motorhomes)

• Diesel Gelling: Diesel fuel thickens in the cold, clogging lines and preventing starts. 

Heating & Interior

• Furnace Failure: Dirty ignition components or improper operation can lead to no heat.
• Propane Issues: Running out of propane unexpectedly leaves you freezing. 

We Recommend These Prevention & Solutions Tips:

• Winterize: Drain all water, use RV antifreeze, and use RV covers.
• Ventilate & Dehumidify: Allow airflow to prevent moisture buildup.
• Protect Batteries: Keep them charged, or store them in a stable environment.
• Inspect: Regularly check tires, seals, and roof.
• Seal Entry Points: Block pests with traps or repellents.
