| Last Updated: July 23, 2022

Are you planning a road trip and looking for the best way to travel comfortably? If so, you need to ensure you get a good quality insulated travel trailer.

Traveling is something that has to be done right. Otherwise, it’s just time wasted, and you get even more frustrated afterward. Stuck in a stuffy vehicle for extended periods of time is certainly not the traveling experience you want. 

Insulated trailers are designed to keep you warm or cool, depending on the weather conditions. They also provide a lot of storage space, which is perfect for long trips.

In this review, we look at some of the best insulated travel trailers, 5th wheels, and motorhomes. We also explain what to look for when sizing up any RVs insulation properties, so you'll have a much better idea of what to look for.

So, with that said, let's dive straight in...

How Important is it That Your Travel Trailer is Insulated?

It is of essence that when you purchase a travel trailer, that it's insulated. There are certain reasons to put into perspective. These are mentioned below.

Hot and Cold

Insulation for shiver-striking weathers becomes crucial when you go for any RV when traveling. It keeps the inner atmosphere warm and pleasant. It also avoids any cold shards of wind seeping through the tiny spaces.

It's equally important for warmer weather as well, knowing well that the best travel trailers have inbuilt air conditioning units. Insulation prevents the rise in temperature and manages to keep the cool air inside as well.

Energy Efficient

Apart from being better for habitants traveling in a travel trailer and maintaining a comfortable temperature, insulation cuts down energy utilization costs. When the heat or cool air doesn't escape the travel trailer, less energy is used to maintain preferred temperatures. Hence, insulation is pocket-friendly and lets you enjoy your adventure without having to worry about the mounting bills.

Water and Fire Resistant

Foam board insulation is the most common type used in your homes and travel trailers, and they're water and fire-resistant. This means you do not have to worry about your trailer walls getting soggy from condensation when traveling in humid conditions. Insulation acts as a safety shield for your travel trailer, keeping you far away from harsh environments or conditions.

What to Look For When Buying an Insulated Travel Trailer

There are certain factors to keep in mind when looking for insulated travel trailers. Here are some pointers to look into.


As mentioned above, the best travel trailers must have the best quality insulation. It's quite difficult to maintain comfortable temperatures without them. It's also crucial to inspect the type of insulations used in an RV. There are many forms, the three most common ones being spun fiberglass, Styrofoam, and Foam-cor. Most of the travel trailers have fiberglass or foam insulated walls in them.

Insulation is measured by its R-Value, which means the higher these values are, the more tendency the walls have to be thermal resistant. So far, fiberglass has proven to be the best of all as it manages to keep constant temperatures.

Floor Plans

This defines the whole layout of the travel trailer. There is no one-for-all travel floor plan that everybody loves. The more varieties of floor plan a trailer has, the higher the number of customers it attracts. These are the most significant part of the trailer as people tend to experience them the most. Hence, it must be of the liking of the customer.

Usability of Space

It's imperative that the floor plan is practical, especially when the vehicle is on the move. Know the answers to important questions like if there is enough space to move around and if the small kitchen is workable in the small space provided.

Having too many fancy items inside this space can make things stuffy, especially when you have your little ones alongside. Access to the bed, kitchen, and bathroom without turmoil is of key importance.


Insulating the water and septic pipes are of value as well. It is best that your travel trailer has PVC pipes for both purposes. Insulated pipes prevent the water from freezing and help you to avoid unnecessary pit stops to the workshop.

The Arctic Fox is one of the best campers. Its wide floorplan is quite spacious as it gives room to move around easily. This travel trailer is known for its insulation, as it is fully welded and has three types of insulations installed.

The walls and skirtings have foam board and fiberglass, whereas the rooftop is completely foiled.

This Class C motorhome has been any family’s favorite as it is handcrafted for such use. From great aesthetics to innovative floor plans, this travel trailer beats many. The indicator lights in the back and sides give an indication of presence to passersby. It comes with great storage space with room under the bed and in the exterior dock.

Best Insulated Trailers FAQs

Is it important to insulate my RV?

Insulating your travel trailer or camper is really important, as it will help you moderate the temperature whether it's summer or winter. The best RVs will come with good quality insulation, but if you have to do it yourself, it's best to insulate the walls and floor if you can.

What type of insulation should I use for my RV?

Fiberglass insulation is the best to use. Most RV manufacturers use fiberglass as insulation, but if you're doing a camper conversion and need some, you should use fiberglass. It will help maintain and moderate the temperature in your vehicle, so you'll be able to stay in your RV comfortable in the summer or winter.

Do you need to insulate your campervan flooring?

The short answer is yes! Insulation is critical to maintaining a comfortable temperature, and your RV will lose heat through a thin flooring. Freezing cold air will also seep in through your thin flooring if you don't insulate the RV's flooring.

How do you live comfortably in an RV in the winter?

If you're in your insulated camper and it's still cold, there are other steps to help you keep warm. You can change the windows to dual pane windows, if they're not already. Also, you can put an insulated mat over any vent, as this will stop cold air getting in.
