Is Winterizing Actually Necessary?
If you live in an area where temperatures drop below freezing, the answer is a definitive yes. Even a single night of a hard freeze can cause water lines to burst, pump seals to crack, and water heaters to fail, leading to thousands of dollars in repairs come spring.
Don't gamble on an "early freeze warning" catch-up session. If your RV isn't climate-controlled or actively heated, you must displace the water in your plumbing system with RV-specific antifreeze.
Calculating Your Pink Stuff Needs
First-time winterizers often ask, "How much pink stuff do I need?" While it varies by floor plan, a safe rule of thumb for most travel trailers and fifth wheels is two to three gallons.
Always ensure you buy propylene glycol-based RV antifreeze, which is non-toxic. Never use automotive antifreeze in your drinking water system, as it is poisonous and nearly impossible to flush out safely.
Choosing the Right Storage
When choosing between outdoor, covered, or indoor storage, consider your climate and your budget. Indoor storage is the gold standard for protecting against UV damage and heavy snow loads, while covered storage offers a great balance of ventilation and protection from the elements.
If you are planning long-term storage, look for facilities that offer pest control and security. For those in regions that experience moderate winters, secure outdoor lots like those found at Hidden Valley RV Resort can be an excellent cost-effective option.
If you are near Pine Ridge Campground, their seasonal storage options are worth investigating to ensure your rig remains accessible yet protected throughout the off-season.
Step-by-Step Winterization Checklist
- Drain the fresh water tank, grey tank, and black tank completely.
- Bypass your water heater to prevent wasting gallons of antifreeze filling the tank.
- Use an air compressor to blow out the lines if you prefer, or move directly to pumping antifreeze via the water pump intake.
- Open each faucet one by one—starting with the one furthest from the pump—until you see the pink stuff flowing steadily.
- Don't forget the outdoor shower, toilet flush, and the P-traps in your sinks and shower.
