Plumbing and Antifreeze Essentials
The most critical step in winterization is protecting your plumbing system. For first-timers asking how much "pink stuff" is needed, the general rule is to have at least two to three gallons of non-toxic RV antifreeze on hand for a standard mid-sized trailer.
- Drain all fresh, grey, and black water tanks completely.
- Bypass your water heater to avoid filling its tank with antifreeze.
- Pump antifreeze through every faucet, including the shower and outdoor kitchen, until you see the pink color.
Tires and Parking Surface
Your tires take a beating during storage if left sitting on cold, damp concrete or dirt. Parking on raised blocks or wood boards prevents moisture wicking, which can accelerate rubber rot.
Always keep your tires inflated to the manufacturer's recommended PSI. If you are storing for an extended period, consider using tire covers to protect them from UV degradation, which occurs even in cloudy winter months.
Heating and Interior Care
Many owners wonder if placing a heater under the trailer is a good idea. While it can prevent frozen pipes, it introduces significant fire hazards and requires a reliable power source. It is safer to focus on complete system drainage.
For interior storage, check for hidden areas like drawers under beds. If you notice signs of moisture, remove items to improve airflow. Proper ventilation is key to preventing mold and mildew while your rig is sealed for the season.
