Across Nova Scotia, more people are choosing RVs as year-round homes, whether it’s for freedom, affordability, or simply a different way to live. But winter RV living brings its own set of challenges.
Freezing temperatures can be hard on water lines, tanks, and heating systems if you’re not prepared. With a few smart upgrades and some cold-weather know-how, you can stay warm, safe, and comfortable all season long.
1. Keep Water Flowing
Your plumbing is the most vulnerable part of RV life in winter.
Wrap exposed lines with heat tape that includes a built-in thermostat.
Insulate supply hoses or replace them with heated RV water hoses.
Keep your water pump and filter compartment warm with small heating pads or low-wattage bulbs.
Always keep your fresh-water tank at least one-third full, it helps prevent freezing and protects the pump.
If you rely on an external water source, check connections regularly for slow drips or ice buildup that could cause blockages overnight.
2. Insulate From the Ground Up
Most RV floors and underbellies aren’t designed for deep freezes.
Add skirting around the base of your RV using foam board or vinyl panels to block wind.
Lay foam mats or rugs over cold floors to retain heat inside.
Seal gaps around slide-outs and entry steps to stop drafts.
Even simple insulation can make a big difference in comfort and fuel savings. For more ideas on protecting your systems, see Top 10 Must-Know Tips for Winterizing Your RV and Camper Water Systems.
3. Protect Your Holding Tanks and Lines
Your grey, black, and fresh-water tanks need extra attention during freezing weather.
Use non-toxic RV antifreeze in waste tanks and traps.
Heat-trace or insulate tank outlets and sewer hoses.
Keep valves closed until tanks are ready to dump, then drain quickly to avoid ice buildup.

4. Seal Drafts and Manage Moisture
Condensation is a common issue during winter RV living, especially in smaller spaces.
Add weatherstripping around doors and windows.
Install Reflectix or foam insulation in window frames.
Run a small dehumidifier or crack a roof vent when cooking or showering.
Managing moisture keeps your RV comfortable, prevents mildew, and helps insulation work effectively.
5. Stay Warm, Stay Safe
A reliable heat source is what makes winter RV living possible, but safety and efficiency go hand in hand.
Test propane detectors, smoke alarms, and carbon monoxide monitors.
Keep furnace vents and exhaust ports clear of snow or debris.
If using space heaters, plug them directly into outlets (never power strips) and place them away from fabrics.
Have backup options like extra propane tanks, heated blankets, or a small generator for emergencies.
Taking these extra precautions helps ensure you stay warm through every cold snap, without risking safety or system strain.
Winterizing Your RV Keeps You Ready for Life on the Road
With the right prep, winter RV living can be comfortable, affordable, and even cozy. Insulation, safe heating, and water-line protection are the key ingredients to making your RV feel like home, no matter how cold it gets outside.
