Cold for Camping in an RVTraveling in an RV at low temperatures is challenging. An RV is equipped to manage the winter elements. Staying in an RV is problematic when temperatures drop below 20 – 32 degrees Fahrenheit.

If the temperature drops below 24 degrees Fahrenheit overnight and remains below freezing during the day, your RV is at risk.

What Are Some Issues That Can Be Caused Due to Coldness?

The cold weather will significantly impact your RV. You must understand how a temperature drop will ruin your journey and even place you in danger.

Extreme cold affects the water pipes, black water tanks, batteries, heating systems, and engines- additionally, cold causes mold, which negatively impacts your health.

too Cold for an RVYour Engine Fails Due to The Cold Temperature

Your RV’s engine won’t start, stall, or turn over. Your RV’s alternator belts will crack under the cold. Broken alternator belts will prevent power from running to your battery.


The Strain on Your RV’s Heating System

A drop in temperature increases the need for heat. The below-average weather conditions demand more from your RV’s heating system. Hypothermia or increased frostbite risk will result if the RV’s heating system fails. Frostbite can occur within minutes and is mainly due to fluctuating temperatures. Keep your RV in the sun wherever possible to rest your RV’s heating.

The heater in your RV is a forced air heater. When temperatures drop below freezing, the heating system in your RV automatically pushes hot air through the vents. When the atmosphere becomes too cold, the reliance on the heating system takes a toll on your RV.

The RV’s heating system is simple and efficient. In addition to the thermostat and fan, there is a safety limit switch, circuit board, sail switch, duct design, intake vents, and exhaust vents. Some RVs have hydronic heating systems that move water and antifreeze through radiators and pipes. The engine heats the water while driving.

Usually, RVs have either an electric system or a propane heater. It’s advisable to bring along additional heaters. Propane space heaters and catalytic heaters are safe and suitable. Electric heaters vary, including infrared, oil-filled, ceramic, and micathermic heaters.

Infrared heaters radiate electromagnetic energy and generate heat to various physical aspects of the RV. Oil heaters are subtle and effectual, keeping the space at a steady temperature. Ceramic heaters use more energy. Finally, micathermic heaters have internal panels lined in mica, which effectively transmits heat.

Safety is the priority. Leaks from a propane heater are deadly. Therefore, acquire a propane detector and a carbon monoxide detector. Airflow is crucial when the forced air heating system turns on. Therefore, ensure vents are uncovered.


Draining Your RV’s Battery

Your RV’s battery is a chemical reactor, and the cold weather will decrease the battery’s electric conversion. Furthermore, the surrounding freezing air will solidify the oils and lubricants in your engine- the cold increases engine resistance, demanding more from your RV’s battery.

The cold will ensure you rely too much on your battery for various electrical output appliances, like heaters. Over-reliance reduces the lifespan of your battery. Additionally, too much use will drain the battery’s charge, preventing it from fully recharging. Sulfation arises when a battery can’t recharge adequately.

Sulfation is a buildup of lead crystals, and this rapidly drains your RV’s battery. When a battery doesn’t fully recharge, the lead crystals inhibit the conversion of chemical energy into electrical energy. Sulfation can also result from overcharging and storing it with an empty charge.


Burst Water Pipes and Frozen Holding Tanks

Too cold for an RV is when the RV’s pipes and plumbing system freeze. When water freezes, it expands in volume, causing burst pipes. Frozen pipes need replacement, which is expensive. Burst pipes damage the interior of your RV, creating a mess and contributing to the overall cost.

Some RV manufacturers design their motorhomes with plumbing systems outside in a storage compartment. Here the pipes will certainly freeze and likely burst. Keep this in mind when buying a suitable RV. Also, open your kitchen cabinets when possible, especially at night, as the warmth will naturally move to these areas.

Protect your RV’s water pipes and holding tank. Completely drain your pipes. Dry your electric heated hoses before storing them. Some RV’s waterlines and tanks have heating pads or attachments. Ensure your RV is well equipped.

Another excellent way to protect your RV’s internal plumbing system is with heat tape on the pipes. You can install heat tape yourself or have it professionally done. It’s fast and straightforward to install, yet it must be thermostatically controlled, as it could damage your plastic pipes.

Tanks freeze in the icy weather. A consequence of the extreme cold is that your RV’s black water tank will freeze into a frozen solid or burst. You must wait for the contents to thaw before disposing of them. A holding tank heater will combat the cold. Another method is to pour non-toxic RV antifreeze into the tank via the p-trap and toilet.

Ensure your black water tanks aren’t filled before the weather drops below freezing. They must be one-third filled or have enough space to accommodate volume expansion when freezing. Add RV antifreeze which will lower the freezing temperature of the water.


Mold in Your RV

Cold weather causes condensation and mold problems. Condensation results from vapor, warm air, and a cold surface. If the condensation isn’t managed, mold forms on your RV’s linen, bedding, and mattress. Mold is difficult to remove and hazardous to your health.

Insulate the mattress bed frame, use a coir bed mat, or install a Froli system under the mattress. A coir bed mat is made from natural materials and is affordable. The Froli system is plastic, with many separate pieces. There is also anti-mold paint that effectively protects your bed space.


Insulate Your RV for Better Performance in Cold (and Warm) Weather

etter Performance in Cold WeatherInsulate the walls, ceiling, and floor in your RV. Some campers aren’t built for below-zero-degree temperatures. Reinforce the insulation you have and upgrade where necessary. Be mindful that your RV’s insulation and overall amenities deteriorate in the cold.

The following are ways to insulate your RV:

  • Seal your camper’s doors and windows. You can fasten your door with high-quality weather stripping.
  • Insulate your motorhome’s windows. There are inexpensive ways to insulate your RV’s windows, like reflective foil or film. The reflective foil redirects heat into the RV.
  • Thick fabric and heavy drapes are practical insulation measures. Watch out for mold. Heavy drapes can partition sections of your rig, keeping the heat in a small space for longer.
  • To insulate your camper’s floors, use foam floor boarding, heavy rugs, and carpets.
  • Place RV skirting or windskirting around the bottom section of your motorhome.
