To Winterize or Not? Understanding Complete Winter Storage
As the temperatures drop, every RVer faces the inevitable question: do I need to completely winterize my rig? If your storage location experiences sustained temperatures below freezing, complete winterization is not just recommended—it is essential to prevent catastrophic plumbing failures.
Skipping steps like clearing out your water lines can lead to cracked pipes, ruined water pumps, and expensive spring repair bills. Even if you live in a milder climate, occasional hard freezes can catch you off guard. Taking the time to properly prepare your motorhome or travel trailer ensures peace of mind all winter long.
Plumbing Prep: How Much Pink Stuff Do You Need?
First-time winterizers often wonder how much RV antifreeze they actually need to buy. For a standard 20-to-30-foot travel trailer or motorhome, purchasing two to three gallons of non-toxic RV antifreeze (the pink stuff) is usually enough to treat the lines, traps, and holding tanks properly.
If you plan on using the blowout method with an air compressor first to clear out bulk water, you might use even less. Always bypass your water heater before pumping the antifreeze through the system to avoid wasting gallons of fluid filling up that large tank.
- Drain your fresh water, grey, and black tanks completely.
- Drain and bypass your water heater to protect the anode rod and tank.
- Blow out remaining water using compressed air at a regulated 30 to 40 PSI.
- Pump RV antifreeze through every faucet, showerhead, and flush valve until you see solid pink fluid.
Protecting Tires, Roofs, and Storage Spots
Your tires take a beating during storage due to weight distribution and UV exposure. Inflate your tires to their maximum PSI before parking, and use tire covers to block harmful UV rays if your rig is sitting outdoors. Alternatively, parking on blocks or levelers prevents flat spots from forming on concrete or frozen ground.
When evaluating where to store your rig, consider moving to a covered storage spot if budget allows. Covered storage protects your rubber roof from snow loads, ice dams, and sun degradation, drastically extending the lifespan of your RV's exterior seals. Avoid the temptation to place a heavy-duty electric heater directly under your trailer unless it is rated for unattended continuous use and fire safety, as space heaters pose serious hazards in storage environments.
