Extreme Cold Weather RV: Best RVs for Cold Weather RVing
Most RVers avoid cold weather camping, either by traveling to warmer climates or by winterizing and storing their RVs until spring. A growing segment of the RVing community, however, is choosing to brave the winter weather for full-time rving in cooler climates.
As a future RV owner, choosing the right RV for your cold-weather adventure makes all the difference. Many manufacturers claim their rigs are suitable for four-season use, but it can be hard to sort through the rhetoric to know if you will truly be comfortable.
Not all “Arctic packages” are created equal. Before your winter wonderland turns into a bone-chilling nightmare camping trip, be sure to do your homework and know exactly what to look for in a cold weather camper.
Things to Consider for Cold Weather RVs
Insulation is a well-known and very important factor in cold-weather comfort. The right insulation will keep the warm air inside and the cold air outside, even in freezing temperatures when icy winds blow.
Insulation is measured with an “R-value” that indicates how resistant a material is to conducting heat. In other words, the higher the R-value, the better the insulation is.
There are three common types of insulation found in most RVs: fiberglass, rigid foam, and spray foam. Of these, fiberglass has the highest R-value, followed by rigid foam. Spray foam has the lowest R-value.
When considering RV insulation, remember that moisture tolerance is also a factor. Fiberglass is better suited to dry conditions, as moisture reduces its effectiveness and leads to a shorter lifespan. Rigid foam has a lower R-value, but it is moisture resistant and long lasting. Spray foam is unaffected by moisture, lightweight and inexpensive, but its low R-value makes it a poor choice for winter camping.
Well-insulated walls are important, but a true four-season RV will also have well-insulated floors and ceilings. If the rig has slide-outs, be sure to find out how these specific areas are protected from the elements.

RV Heating System
If the insulation is effective at keeping cold air out and warm air in, then the next factor to consider is how that inside air is being heated in your winter camper.
The standard in most RVs is forced-air heat from a propane furnace. A clear advantage to propane heat is that it does not require a connection to shore power for the heater. This is helpful if you have plans to boondock in cold weather. If winter storms knock out the electricity, you can stay warm as long as you have sufficient propane and the battery can continue to run the fans. It is also possible to connect these furnaces to a larger propane tank of your RV trailer for longer stays or to refill without needing to move the RV.
Propane furnaces also consume significant amounts of propane, which can be costly for extended stays in cold climates. For this reason, many winter RVers prefer to use other sources of heat. Heat exchange pumps are often available as a feature in the RV’s air conditioning system. They can also be added aftermarket if desired. These pumps run on electricity, which can reduce costs since electricity is often included in the nightly fee at a campground. But, because these heat exchange pumps do not work at temperatures lower than 40°F, they are of little use in winter conditions.
Electric space heaters can be an excellent way to supplement other forms of heat. They are not powerful enough to heat the whole rig in extremely cold temperatures, but they can help reduce propane usage. Their dry heat helps manage moisture issues, and they can be moved to direct heat to specific areas, such as bedrooms, as needed.
Note: As with any free-standing electric heaters, be sure to have internal safety and risk mitigation steps in place!
Some diesel rigs are equipped with hydronic heat, which can be very expensive but have many advantages in cold weather. These are less common and generally only available on higher-end Class A vehicles.
Heat energy output is measured in BTUs. BTU stands for British Thermal Unit, though ironically this measurement is no longer used in the UK. The higher the BTU number, the more powerful the heat output, so when comparing heating systems this is the number to look for. It is worth noting, however, that bigger is not always better. The heat output required to heat a smaller space is less than what is needed for a larger space, so as long as the heating system is proportional to the size of the rig, a higher BTU is of little advantage.

RV Tanks and Underbelly
Any RV being used in freezing temperatures should have an enclosed, heated underbelly. Inspect any RV you are considering from underneath to see that the underbelly is fully enclosed and sealed against the elements. Water lines and holding tanks should be well-insulated. (fresh water, black water, gray water, etc…).
This is an area where different manufacturers’ “arctic packages” differ considerably. Find out more about how the underbelly is enclosed and heated. Some underbellies are “heated” with little more than an uninsulated furnace duct running through them. Yes, this will increase the temperature slightly, but it will not prevent freezing in prolonged sub-freezing conditions. A designated vent from the furnace will keep the temperature above freezing and the water flowing freely. The best-equipped rigs have pre-installed heating pads and good insulation in key areas such as dump valves and water lines.
Just like in a house, windows are prime areas where heat can escape from an RV and cold drafts can blow in. If a well-insulated rig is a priority for you, then dual pane windows are an important feature to look for. The difference in insulation between single and double panes is significant. Not only does the insulation of dual pane windows help keep you warmer inside, but it also helps reduce condensation and the associated moisture issues. However, the choice between single and double pane windows is not as obvious as it may initially appear.
Dual pane windows insulate well because of the space between the panes that is filled with gas. The vibrations and other motion caused by driving or towing the vehicle cause this gas to gradually leak out, which leads to fogging between the panes of glass. Even on the most carefully driven rig, dual pane windows will eventually fog and need costly repairs or replacement.
RVs with single pane windows can be used successfully for winter camping, but adding insulation to the windows is recommended. There are a variety of aftermarket products available to help reduce heat loss through single pane windows.

A well-insulated rig with a good heating system, an enclosed, heated underbelly, and insulated windows will be sufficient for cold weather RVing. There are some models, however, that are designed with winter in mind and these often add extra features to make the experience easier and more comfortable. While they are not essential, those who use their RVs frequently in cold weather may appreciate these perks:
- Insulated/heated water lines. These can also be purchased separately and added. This feature extends the temperature range for using city water hookups
- Water heater bypass. This can also be purchased separately and added, but having one already installed saves the cost and hassle. This feature makes the process of winterizing or preparing tanks for extreme temperatures much faster and simpler.
- Tankless water heater. Eliminate the need to bypass the water heater at all. A tankless water heater saves energy and guarantees you will not run out of hot water
- Custom RV skirting. Skirting around the bottom of the RV makes a big difference. It is a hassle to set up and take down if you are often moving, but if your rig will sit still for a while in cold weather, RV skirting is very helpful. Custom skirting matches the model-specific measurements and simplifies the process
- Heated mattress. A pure luxury that needs no explanation
There are reasons why many RVs are not built for four-season camping. When shopping for a winter-friendly model, keep in mind that you may need to compromise on other factors that might also be important to you, such as cost and weight.
Higher quality materials come with a higher price tag. Additionally, many cold weather features are the result of more recent technological developments, meaning that they are not available on older, pre-owned models. The best RV models for winter camping also tend to be the most expensive.
Cutting costs is not the only reason that RV manufacturers skip many of the best winter features. Weight is also an important consideration. These features are seldom available on the “light” camper models because added insulation means added weight. Heavier rigs are less fuel-efficient and require more skill to drive safely.
While most available models of RVs are not ideal for use in cold weather, the increased popularity of winter camping is creating a larger market for well-equipped RVs, and manufacturers are beginning to respond accordingly.
