Essential Winterization Steps

If you are facing an early freeze warning, don't wait. Winterizing is non-negotiable if you live in freezing climates. The most common question we get is: how much pink stuff do I need? Generally, two to three gallons of RV-specific antifreeze are enough for most standard travel trailers to flush the lines thoroughly.

While some debate if complete winterizing is necessary, we always recommend it. A single broken water line from a freeze can cause catastrophic internal water damage. Bypass your water heater, drain your low-point drains, and ensure you use non-toxic plumbing antifreeze only.

Storage Best Practices

Proper storage is about preventing moisture and tire degradation. If you are using raised blocks, ensure they are stable and rated for your RV's weight. Avoid the common mistake seen at storage facilities where leveling blocks are misused; always ensure your leveling system or blocks are positioned correctly under the frame or tires.

Regarding tires, keep them off the bare ground if possible, or use tire covers to protect the rubber from UV exposure. For those looking for long-term solutions, consider the benefits of covered storage, which significantly reduces snow load and environmental wear on your roof seals and slide-out gaskets.

Optimizing Your Interior

Many owners experiment with interior modifications like removing drawers under bed storage to improve airflow or access, but ensure any structural supports aren't compromised in the process. Keep the interior clean and remove any food items to prevent rodent activity during the quiet winter months.

Finding the Right Storage Environment

The planning commission recently recommended moving forward with new RV storage facilities, which highlights the increasing demand for secure, dedicated parking. Whether you are choosing an open-air lot or a custom RV storage building, look for facilities that offer adequate drainage, security, and enough space for easy maneuverability.
