To Winterize or Not? Assessing Your Climate and Needs
One of the most common debates among RV owners when the temperature drops is whether complete winterization is truly necessary. If you live in a region where temperatures consistently dip below freezing, bypassing winterization is a gamble that usually ends in cracked pipes and costly repairs. However, if you are parked in a mild climate or utilizing campgrounds for the winter months in the southern states, a full freeze-proof winterization might be overkill.
If you decide complete winterization isn't necessary because you're actively using the rig or keeping it heated, you still need a solid monitoring plan. A sudden unseasonal deep freeze can catch you off guard. Always weigh your local historical freeze data against the hassle of blowing out lines and adding antifreeze.
Mastering the Plumbing: How Much Pink Stuff Do You Need?
First-time winterizing often brings up a lot of anxiety, particularly around the famous question: how much pink RV antifreeze do I actually need? As a general rule of thumb, most standard travel trailers and motorhomes require about two to three gallons of propylene glycol (the pink stuff) to adequately protect the plumbing lines, traps, and holding tanks.
- Drain your fresh water tank, grey tank, and black tank completely.
- Bypass your water heater using the installed bypass valves to avoid wasting gallons of antifreeze trying to fill the tank.
- Use a blowout plug with an air compressor to clear out residual water from all lines at around 30-40 PSI.
- Pump the pink antifreeze through your system starting from the fixture furthest from the water pump, running each faucet until you see clear pink liquid.
Protecting Your Investment: Tires, Heating, and Storage Spots
Motorhome storage and travel trailer preservation involve more than just the plumbing. Tires are a major investment that suffer greatly from prolonged stationary storage, UV exposure, and ground moisture. To prevent flat-spotting and sidewall cracking, inflate your tires to the maximum PSI recommended on the sidewall, park on leveled blocks or boards rather than bare dirt or grass, and use opaque tire covers.
Another frequent dilemma is whether to place a heater under the trailer in the winter. While some owners swear by skirting combined with a small, monitored electric space heater or heat tape to keep underbelly pipes warm, it introduces a fire hazard and relies entirely on uninterrupted power. If grid power fails during a winter storm, your pipes will freeze instantly. Whenever possible, relocating to indoor or covered storage is a much safer bet than relying on makeshift skirting heaters.
Finally, evaluate your changing storage spots. Outdoor uncovered lots expose your rubber roofs and decals to harsh UV rays and snow accumulation, which accelerates wear. If you can upgrade to covered storage or an enclosed unit, you will save yourself countless hours of spring cleaning, roof sealing, and weather-related repairs.
