15 Features to Look for in a Four Seasons RV

This post may contain affiliate links.

Are you wanting to buy an RV you can use in cold weather? If so, you’ll want to make sure the camper you choose can withstand freezing temperatures, like a four seasons RV. Otherwise, you may find yourself dealing with frozen pipes, spending a fortune on propane, or battling condensation and mold. 

In this article, we’ll cover the issues RV owners face when camping in winter and what features to look for in a four-season RV in order to avoid those problems.

Can you use a “regular” camper in cold weather?

Some RV owners buy a cheap camper planning to live in it in a cold climate, figuring they’ll just skirt the RV and run electric space heaters and everything will be fine. While it is possible to survive cold weather in just about any kind of camper, “an ounce of prevention is worth a pound of cure,” as the saying goes.

Here are some of the issues that can arise when RVing in freezing weather:

  • Frozen pipes and water lines. Many campers—ones that aren’t designed for cold weather—have pipes and water lines exposed to the elements.  If these freeze, they may stop working, or worse, they may burst and leak, resulting in a mess, water damage to your RV, and/or costly repairs.
  • Heat loss through the walls, ceiling, and floor. Campers designed for use in warm weather don’t usually have much insulation inside the walls, ceiling, or floor.  Skirting your RV can help prevent heat loss through the floor, but isn’t convenient for travel. A layer of snow can insulate your roof if you’re in a place where snow stays on the ground all winter. But there’s not much you can do to stop heat loss through your RV walls if they don’t have adequate insulation.  This can lead to the next two problems.
  • Condensation, mold, and mildew. Condensation in an RV results when warm, moist air comes into contact with cold surfaces…like poorly insulated walls. These damp surfaces provide the perfect breeding ground for mold and mildew. Running a dehumidifier may help, but removing the moisture from the air doesn’t solve the problem of cold walls.  Also, dry air feels cooler than humid air, so running a dehumidifier may also mean setting the thermostat to a higher temperature to feel comfortable.
  • Heating cost. Keeping the inside of a large RV at a cozy temperature can easily cost hundreds of dollars per month.  In an RV that’s losing heat through the walls, the heating system will work overtime to keep up.

The idea behind a four season RV like mine (pictured above) is that it is built with these cold-weather problems in mind.

Are four season RVs really four season?

Now that you know what can happen in an RV not built for four seasons, you may be wondering what kind of RV is built to withstand winter. A four season RV is supposed to offer better insulation and protection against freezing compared to typical RVs.

However, not all four season RVs are really four season. There are certain features a four season RV must include to be effective at withstanding freezing temperatures.

What’s the difference between “All Season”, “Four Season”, “Arctic Package” and “Polar Package”?

Terms like “Four-Season”, “Polar Package” and “Arctic Package” are terms RV manufacturers and dealerships use to indicate that an RV is winter-ready. But they aren’t a guarantee—they’re just a starting point. You’ll want to evaluate each of the below features to determine whether it will work for your needs.

Do I need to winterize a four season RV?

If you are storing your RV for winter, yes you should winterize it—even if it’s a four season RV. This will protect your pipes all winter long and avoid costly repairs.

15 Features to Look for in a Four Seasons RV

Following is a list of features available in some RVs that help them withstand freezing temperatures.  Look for these features when considering an RV to buy if you plan on camping in cold weather. 

Before buying an RV that’s missing one or more of these features, research potential ways you can modify the RV to better prepare it for cold weather.

Features that Protect the RV’s Plumbing System

  1. Enclosed underbelly (no exposed pipes, holding tanks, or water lines under the RV)
  2. Water hose connection point and/or dump valves for emptying holding tanks located in an enclosed, heated area. You’ll also want to buy a heated water hose or wrap your hose with electrical heat tape and foam pipe insulation.
  3. The area where the water heater and water lines are located is heated.
  4. Sewage pipes all drain downhill so that no liquid can become trapped and freeze.
  5. Holding tanks are enclosed and/or heated. You can also buy tank heaters to install yourself if yours are exposed and unheated.

Features that Reduce Heat Loss

  1. Extra insulation in walls, floors, and ceilings. Look at the R-values to compare the insulation with other RV models. (Learn all about R-values before you shop in this article about the myths surrounding RV insulation). Walls with a layer of foam insulation in addition to or instead of fiberglass insulation are better at holding in heat.
  2. Enclosed underbelly (This provides an extra barrier to prevent heat loss through the floor.)
  3. Heated underbelly (Heating elements or heater vents keep pipes and waterlines inside the enclosed underbelly warm.)
  4. Ducted storage bay area (Heater vents blow into the storage area under the RV.)
  5. Furnace ductwork runs through the floor.
  6. Double-pane windows (Single-pane RV windows can be insulated, if this feature isn’t included)

Other features that help RVs withstand cold weather

  1. 30k+ BTU propane furnace
  2. An electric “fireplace” as supplemental heat
  3. Attic vents to reduce humidity and prevent condensation
  4. Cold weather protection for refrigerator

What kind of cold weather RVer are you?

In order to determine which cold weather features you need, think about how you’ll be using your RV.

If you only take the occasional fall camping trip, you won’t need much cold weather protection. For full-timers planning to live in an RV where the temperature stays below freezing, you will want all or most of the above features.

If you will be in a climate where the temperature drops below zero, you will need every possible protection. And you’ll probably need to do some additional modifications to prepare for winter as well.

Another important consideration is how frequently you plan to travel in cold weather.  If you will be staying in one place all winter long, you can skirt your camper to help protect it from the elements. 

But if you plan to move on a regular basis, you may want to consider an RV that doesn’t require too much in the way of cold weather preparation. You may consider investing in transportable RV skirting to further protect you.

By thinking through the effect freezing temperatures may have on your RVing experience, you can weigh the cost and benefits of buying an RV that is designed to withstand the cold.

Where to Find Four Seasons RVs for Sale

You can likely find four season RVs at your local RV dealership, but for a better range of options and models, check out sites like They specialize in all-weather RVs and are a good starting point for figuring out which models offer the features you need.

Trusted brands like Arctic Fox are known for producing four season RVs, but most major manufacturers will offer some cold weather rigs. Keep this list handy to remember which features to look for as you shop.

  1. I just bought a motor home last year all this is new to me and any advice I can get is great cause I know nothing about full time Rving. Thank you.

  2. Your winter RV material is extremely important for ANY buyer/owner to understand because an overnight cold front can drop temperatures +40 F. For example 65 F daytime dropping to 35 F overnight. An unprepared RV can quickly become VERY UNCOMFORTABLE when the owner wants comfort the most. You articles come up short on several brutal facts of life.
    1. Most effective cold weather facilities are provided in DESIGN AND BUILDING; NOT bandaid afterthoughts.
    2. There are no legal cold weather standards that allows unscrupulous builders to claim ANYTHING and not be held legally liable.
    3. No manufacturers TEMPERATURE TEST THEIR PRODUCTS. So they have no idea how they will perform in cold weather.
    4.. RVs requiring “winterization” are rendered useless to their owners for several months each year and incur costs to the owner for the privilege. Buying all-season makes economic sense but is very difficult to do.
    5. The only way to assure performance is through TESTING BEFORE making final payment for any RV purchase. Caveat Emptor.

    1. I agree with you 100%. Most RV’s, including “four-season” ones, are really not designed to be lived in full time in brutally cold weather, and those that are haven’t necessarily undergone rigorous testing in realistic conditions. Yet due to economic conditions in the United States and other factors, many people are turning to RV’s as a housing solution out of desperation and finding themselves relying on creativity and resourcefulness in order to survive in all kinds of campers, including those that weren’t designed with any thought given to cold weather use. While it’s definitely important for those setting out to purchase an RV to set realistic expectations and understand that almost no RV will be the same as a house in cold weather, my perspective from personal experience with living in a camper through the winter is that some cold weather features are better than none, and a “bandaid” approach to supplementing where their RV is lacking can make a big difference in keeping someone who is stuck living in an RV for the winter for whatever reason stay warmer than they would otherwise.

      1. We both agree. “Caveat Emptor” places the primary responsibility on the buyer to get what he has paid for. Many posted complaints come from owners who hand a check to the vendor and leave with no inspection or testing, only to discover serious defects in their purchase later. Lazy buyers get what they deserve. But, beyond that, I object to the blatant false advertising rife in the industry: Advertising with pictures showing RVs in scenic spots they could not get to and exotic names for products that don’t remotely live up to their images. The only solution I see is an informed consumer who demands a better product before handing over his hard-earned savings.
