Ventilation Fan

For many, installing a ventilation fan is one of the first steps when building a DIY camper van. These fans are critical to expelling stale air and bringing in fresh, cool air into your van. Not to mention that vent fans help to reduce pesky condensation and mold growth.

Here are our recommendations.

1.1 - Popular Fan Models


The Maxxfan is our top pick for vent fans. That’s because it comes with a sleek, low(ish) profile rain cover, allowing you to use this fan even when it’s rainingoutside.

Fan-Tastic Fan

If price is a concern, the more affordable Fan-Tastic vent fan is another popular option.

This fan is also popular among stealth campers since it’s hood is much more streamlined and less visible from the road side.

The hood, however, is not a rain cover and it must be closed when it’s raining outside.

1.2 - How To Install A Vent Fan

Putting in a vent fan is no easy feat.

It involves precise measurements, cutting through sheet metal, and correct electrical wiring. Not to mention, you only have ONE SHOT at the installation process.

It can get pretty stressful.

Windows specifically made for camper vans & RVs come in all different shapes and sizes. Two of the most popular vehicle window suppliers are:

Installing windows in a camper van can be tricky!

You have to make sure all measurements are accurate and level. And you’ll likely need to cut through several panel support beams, which are thicker than standard sheet metal.

Insulating your camper van is a critical step in the van conversion process.

A common misconception is that insulation is only to help keep the van interior warm when it’s cold outside. But insulation also helps to keep your van cool during hot days, especially when the sun is shining directly down onto the van’s roof.

3.1 - Common Insulation Materials

There are so many different options when it comes time to insulate your van. Common insulation materials include:

  • Reflectix
  • Foam Boards (Polyiso & XPS)
  • Sheep’s Wool
  • Spray Foam
  • Duct Insulation
  • 3M Thinsulate

But how, and where in the van, do you install these materials?

3.2 - Installing Insulation In A Van

In our insulation installation post, we review all the different insulation materials we used in our van.

Then detail how we installed over SEVEN different types of insulation all throughout out van.

From sub-zero temperatures in the American west to blazing hot beaches in Central America, our insulation has kept up with our needs.

Walls & Ceiling

If you haven’t already, we encourage you to create an interior color scheme for your van. This will help you decide what materials and color your walls and ceiling will be.

Once you’re ready to install, keep reading our step-by-step guide below.

4.1 - Install Furring Strips

Screwing your walls and ceiling boards directly into a van’s sheet metal frame isn’t ideal. That’s because the pull-out strength of screws on sheet metal is extremely low.

Not to mention that you’d be exposing bare metal, which is a rust hazard.

That’s why we recommend installing furring strips throughout the van with cross nuts. ZERO holes are created and you have a substantially higher (>10x) pull-out strength.

4.2 - Plywood Wall Installation

We love our camper van walls.

They’re space efficient, streamlined, and brighten up our van’s interior.

In our van wall installation post we detail our step-by-step process of how we measured, cut, mounted, and painted our plywood walls.

50,000 bumpy miles later, our walls are still hanging on like the did on Day 1. Read our post to learn more.

4.3 - Cedar Plank Ceiling Installation

We love our cedar plank ceiling. It’s one of our favorite aspects of our van build.

To learn how to install a beautiful cedar plank ceiling in a camper van, check out our post.

We give helpful advice on how to select the wood, stain the wood, and attach the boards to the ceiling furring strips.
