How to Find the Best 4 Season Travel Trailer

82

Camping is usually associated with fair weather conditions, but the temperatures you’ll encounter at different destinations aren’t always ideal. Finding the best 4 season travel trailer will make you better prepared for boondocking in different climates.

Most families take their travel trailers out of storage a few times per year, usually during months with moderate temperatures. That’s why most campers don’t pay much attention to the travel trailer’s insulation, heat transfer properties, or heating system.

However, full-time RVing also involves camping in subzero temperatures, which is impossible if you have a 3 season travel trailer. That’s why in this article, we’re going to show you how to find a four-season travel trailer that will keep you comfortable regardless of the weather conditions at a campsite.

What is a four-season travel trailer?

Brands rarely market their products as four-season travel trailers, but rather equip them with features that make them suitable for use throughout the year.

The vast majority of travel trailers are designed to be used from early spring until the late autumn, but keeping a 3 season travel trailer cool during hot summer days can be challenging even if it has an AC system.

The reason for this is the lack of insulation in the walls, floor, and roof of three-season travel trailers, which allows a heat transfer from the outside into the trailer’s interior.

Models that are well insulated and have good heat retention capabilities are known as four-season travel trailers since the hot or cold air from the outside doesn’t affect the room temperature.

These models also feature specially designed doors, windows, and hatches that prevent heat loss and keep the travel trailer’s interior warm. Check out our guide to medical insurance for snowbirds if you prefer to spend winter months in regions with mild climates.

The most common types of insulation

4 Season Travel Trailer

The insulation is by far the most important feature of a four-season travel trailer, especially if you’re considering full-time RVing. Manufacturers utilize different types of insulation to regulate the temperature inside a four-season travel trailer.

Consequently, each model will have an R-value rating that indicates the thermal resistance of the insulation material. The four-season travel trailer with a high R-value rating will remain cool during summer and warm during winter.

Fiberglass, rigid foam, and spray foam are the most common types of insulation you’ll find in travel trailers, and each of them has slightly different properties. Fiberglass insulation is probably the most common, and it is almost a standard for most motorhomes.

The R-value rating of this insulation material is fairly high, but it isn’t durable, and moisture can damage it easily. So, if you’re changing climates frequently, you should consider a four-season trailer that has rigid foam insulation.

But, you should keep in mind that the rigid foam insulation material is more expensive than fiberglass or spray foam. It is also worth noting that you should avoid four-season travel trailers insulated with spray foam because the material’s R-value rating is low.

Thermal break properties

The material placed between the walls can allow or interrupt the flow of heat from the outside into the travel trailer’s interior. The term thermal break refers to the material’s ability to prevent two materials from inhibiting cold or heat onto each other.

Hence the material that is placed between the walls of a four-season travel trailer needs to have good thermal break properties in order to prevent the transmission of heat or cold from the trailer’s exterior wall onto its interior wall.

Avoid models that have wooden panels or metal stud framing between walls because these materials don’t resist the flow of thermal energy and as a result, the travel trailer can become incredibly cold or warm when exposed to high or low temperatures.

Heat retention features

Nearly all modern travel trailers are equipped with a heating system that contains a furnace capable of producing tens of thousands of BTUs.

These furnaces work as forced air heaters that push warm air every time the heating system’s thermostat detects that the room temperature has dropped below the preset temperature.

However, if a travel trailer has poor heat retention features, the heating system will fail to keep its interior warm regardless of how powerful it is. The same is true for the trailer’s AC system that will consume an enormous amount of power while trying to keep the trailer cool.

Four-season travel trailers feature shells that prevent heat loss, making their heating and cooling systems more efficient. In addition, the shell’s heat retention capabilities reduce the amount of electricity or fuel you have to use to warm up or cool down a four-season travel trailer.

Low-temperature resistance of key systems

Sustaining yourself without some of the travel trailer’s key systems is impossible because you need access to running water or electricity to live normally.

The problem is that the systems that enable you to watch a TV or wash dishes in a travel trailer are not always resistant to freezing, as exposure to subzero temperatures can cause them to freeze and ultimately damage them.

That’s why a four-season trailer you choose needs to have a conditioned basement, a compartment located beneath the floor that houses the water tanks, valves, electrical installations, and all other systems that are vital for the trailer’s normal functioning.

The heating system is usually based in the conditioned basement, and once you switch it on, it draws the hot air from the trailer’s main compartment into the basement, which ensures that all other systems are kept at operating temperatures.

Four season travel trailers solve the snowbird issues

Most full-time RVers deal with cold weather conditions by temporarily moving to a warmer climate region. Getting a four-season travel trailer will enable you to camp during cold months, which can be very important if you need to spend a winter in one place because of work.

Offers full-time RVers a high level of comfort

Four-season travel trailers can provide full-time RVers with a comfortable home because they feature a broad spectrum of features they might need while on the road, besides excellent insulation and heat retention capabilities.

The disadvantages of four season travel trailers

Four season travel trailers are more expensive than regular travel trailers

You will have to spend tens of thousands of dollars to get a travel trailer that is equally functional during all parts of the year. In addition to considerable upfront investment, you will have to spend significant funds on the trailer’s upkeep.

Key factors to consider while choosing a four-season travel trailer

One of the most important differences between a four-season trailer and any other trailer is the insulation material that interrupts the flow of thermal energy. Consequently, keeping a four-season trailer cool or warm requires less energy than heating or cooling any other type of travel trailer.

Although the trailer’s insulation and R-value rating are some of the key factors you need to consider while choosing a four-season travel trailer they’re far from being the only ones. So, let’s take a look at the factors that can help you pick a four-season trailer that meets all your needs.

Comfort level

The comfort level of a four-season travel trailer goes well beyond the model’s heating and cooling features. Go through the list of all amenities that come with the trailer, check how many sleepers it can accommodate, or find out if it has an interior bathroom, before deciding to opt for a particular model.

Warm and cold weather performance

four-season travel trailer

The color of the trailer’s shell or how powerful its AC system is can affect its warm weather performance, while the heater’s BTU or insulation type can help you estimate its performance in subzero temperatures.

Also, you shouldn’t choose a model that will enable you to merely survive in extreme weather conditions, but a four-season travel trailer that will make you feel comfortable even at extremely low or high temperatures.

Window insulation

Parts of a trailer where installing insulation is difficult such as windows or hatch compartments can allow the outside temperature to affect the trailer’s room temperature. That’s why, you should choose a model that has windows, doors, and hatches that prevent heat loss.

The frame design

The so-called trailer envelope or the shell is the component that is most susceptible to heat loss. Checking from which material the travel trailer’s frame, walls, and roof are made might help you understand better how the trailer is going to behave under challenging weather conditions.

Off-grid and on-grid performance

Boondocking in style can drain your energy supply in a hurry. Estimate how much power the four-season travel trailer’s heating system needs to keep the interior warm, to figure out how much propane you need to take with you or how many solar batteries you need to charge.

Also, you can measure how much electricity you’re going to need to keep the trailer’s heating or AC systems running and calculate the additional costs you will have to cover.

Frequently asked questions about four-season travel trailers

Question: Do I need additional power sources for a four-season travel trailer?

Answer: Although some models may feature a solar panel its power output isn’t high enough to meet all your power consumption needs. Getting a generator or installing a solar power system will enable you to stay off the grid for days if not weeks.

Question: Should I empty the water tank during winter nights?

Answer: Most manufacturers don’t issue warranties for damages caused by freezing, so emptying the water tank when you expect the temperatures to drop below 0F will prevent the potential damage.

Question: Can I sleep in a four-season travel trailer even at subzero temperatures?

Answer: Whether or not you’ll feel comfortable in your four-season travel trailer while the exterior temperatures are below 0F depends on the trailer model, its heating system, and insulation type.

Question: Do four-season travel trailers lose their heat retention capabilities in time?

Answer: All insulation materials gradually lose their heat retention capabilities, so the interior of a four-season trailer is going to become colder over time.

Our verdict: Which 4 season travel trailer performs best in freezing temperatures?

Spending the entire year on the road, regardless of the weather conditions can bring you some incredible experiences.

But, regular travel trailers are simply too cold for camping during winter, and you must get a four-season travel trailer if you don’t want to move to a region with a warmer climate during the cold months.

Besides, four-season travel trailers are an excellent option for all full-time RVers, because they bring a high degree of comfort.

We recommend getting the Jayco Eagle Fifth Wheel or Forest River Arctic Wolf four-season travel trailer if you’re searching for a comfortable model that handles heat or cold well.
