To Winterize or Not? Understanding the Freeze Risk
As the temperature drops, every RVer faces the inevitable question: do you really need to completely winterize? If your rig is subjected to freezing temperatures, the answer is an absolute yes. Leaving water in your plumbing lines is a gamble that almost always ends in cracked pipes, ruined water pumps, and costly spring repairs.
First-time RV owners often stress about how much antifreeze they actually need. For a standard travel trailer or motorhome, having two to three gallons of non-toxic RV antifreeze (the pink stuff) on hand is usually enough to flush the lines safely, provided you've thoroughly drained the water heater first.
Is Heating Under the Trailer a Good Idea?
Some owners debate whether placing a space heater or incandescent light bulb under the trailer prevents freezing. While it might help during a brief cold snap, relying on auxiliary heat during a harsh winter is risky. Power outages, extension cord failures, or unexpected severe drops can instantly neutralize your setup. Complete winterization with antifreeze and compressed air blowout remains the gold standard for reliable protection.
Protecting Tires and Choosing the Right Storage Spot
Your RV tires bear the heavy brunt of stationary winter storage. Without movement, tires are prone to flat spotting and accelerated sidewall cracking caused by UV exposure and freezing ground temperatures.
To mitigate tire damage, inflate them to the maximum recommended pressure before parking. Use tire covers to block out damaging UV rays, and consider placing flat-stoppers or rubber mats beneath each tire to create a barrier against cold concrete or damp earth.
Covered Storage vs. Outdoor Options
Deciding where to store your motorhome or trailer depends heavily on your budget and climate severity. Covered storage offers an exceptional middle ground, shielding your roof seals, AC units, and decals from heavy snow loads, ice accumulation, and harsh sun. If you opt for an outdoor lot, invest in a breathable, high-quality RV cover that won't trap moisture and cause mold or mildew growth over the winter months.
Step-by-Step Winterization Checklist
Follow these essential steps to prep your rig efficiently before locking it up for the season:
- Drain the fresh, grey, and black water tanks completely, and bypass your water heater.
- Blow out remaining water from the plumbing lines using an air compressor adapter at a low psi (around 30 psi).
- Pump pink RV antifreeze through all hot and cold faucets, including the shower and toilet, until you see clear pink fluid.
- Pour a cup of antifreeze down every sink and shower drain to protect the P-traps.
- Remove the RV battery, store it in a temperature-controlled area, and put a trickle charger on it.
- Clean out all food items to deter rodents, prop refrigerator doors open, and place moisture-absorbing damp-rid buckets throughout the interior.
