September 15, 2026

Don't let the first freeze catch you off guard. From winterizing your plumbing to tire maintenance, we cover everything you need to keep your RV safe and ready for spring.

Essential Winterization: Plumbing and Heat

The most urgent task before the first freeze is protecting your water systems. While many wonder if complete winterizing is necessary, the cost of burst pipes far outweighs the effort of pumping a few gallons of RV-safe antifreeze through your lines. Most rigs require 2 to 3 gallons of 'pink stuff' to adequately protect the kitchen, bathroom, and outdoor shower systems.

Is Heating Under the Trailer a Good Idea?

RVers often ask about placing heaters under the trailer. While this can provide a buffer, it creates a significant fire hazard and moisture risk. Instead of external heating, focus on sealing slide-outs and using an interior space heater to keep the rig above freezing if you aren't fully draining the system.

Storage Best Practices

Whether you choose covered storage or an open lot, protecting your tires is non-negotiable. Sunlight is the primary cause of sidewall cracking. Always use tire covers, and if your rig will be stationary for months, consider parking on raised blocks or leveling jacks to prevent flat spots from forming on the tires.

Optimizing Interior Storage

If you're looking to gain space or improve airflow, many owners consider removing drawers from under-bed storage. This is a great way to maximize deep access for bulky gear. Just ensure you are cleaning these spaces thoroughly before storage to discourage pests from nesting in your upholstery.

Planning for Your Next Trip

Preparation is the secret to a stress-free travel season. When you aren't storing your RV on your own property, look for professional, secure locations. Facilities like those found at [Hidden Creek RV Resort](/park/hidden-creek-rv-resort) offer excellent amenities for long-term storage needs, ensuring your rig is protected and accessible when the thaw arrives.

Properly winterizing now ensures you spend your first weekend of spring camping rather than fixing leaks. Take the time to check your seals, batteries, and tire pressures before you finalize your winter storage plan.
