Professional Boat & RV Winterizing Services in North Idaho

Winter can be brutal on your watercraft or recreational vehicle. Freezing temperatures can crack plumbing lines, ruin engines, and cause expensive repairs in spring. Alpine Auto & Off-Road offers complete boat and RV winterizing services in Coeur d’Alene, Hayden, and the surrounding areas, helping you protect your investment from North Idaho’s harsh winter conditions.

Why Winterizing Matters

Water left in tanks, lines, or engines can freeze and expand — leading to cracked blocks, burst fittings, and ruined pumps. Proper winterization prevents thousands in avoidable repairs and ensures your boat or RV starts up cleanly next season.

What Our Winterizing Service Includes

Full system flush and drain of fresh water and waste tanks
Engine winterization with marine-grade antifreeze and fuel stabilizer
Inspection of seals, hoses, and fittings for leaks or wear
Battery removal and storage recommendations
RV plumbing and appliance protection
