Plumbing Protection: The Pink Stuff

The most critical step in winterization is protecting your water lines from freezing. The age-old question is how much RV antifreeze—or "pink stuff"—you actually need. For most travel trailers and fifth wheels, three to four gallons is typically enough to clear your lines and traps.

If you live in a region with extreme, prolonged deep freezes, do not skip this step or attempt to rely solely on air blowout methods. Always ensure you bypass your water heater before pumping the solution, otherwise, you'll waste gallons filling that tank unnecessarily.

Tire Care and Parking Techniques

Tires During Storage

Leaving tires on cold, damp concrete or dirt all winter can cause them to rot or develop flat spots. If your storage facility allows, place your RV on heavy-duty plastic or rubber blocks to separate the tires from the ground. This simple barrier helps prevent moisture wicking and tire degradation.

Parking Best Practices

We have all seen the "creative" parking at facilities—like using Anderson levelers as permanent chocks or parking haphazardly. Always ensure your RV is level and properly chocked using manufacturer-recommended gear. If you are storing your RV at a facility like [Mountain View RV Park](/park/mountain-view-rv-park), ensure your leveling blocks are stable and not obstructing access paths for your neighbors.

Optimizing Your Storage

Many owners ask if they should remove under-bed drawers or modify storage areas. While clearing out heavy items can help, the real priority is ventilation. Remove food items, vacuum seal soft goods, and consider using moisture absorbers to prevent mildew.

To Cover or Not to Cover

Covered storage is the gold standard, but if you are using a breathable RV cover, ensure the rig is clean and dry first. Trapping moisture under a cover is the fastest way to invite mold. If you are looking for long-term solutions, consider checking out local options like [Riverside Campground](/park/riverside-campground) that offer designated long-term parking areas.
