Installing the Webasto Heater

Below is the perfect place to install the heater as it doesn't interfere with the structure and such underneath the van. I made measurements to help others.

I'm super glad I had Josh Thebarge of VanlifeOutfitter.com consulting and for him to convince me to get the EVO instead of the STD as I'm digesting many issues with Russian and Chinese heaters and the STD heater at higher elevations and such (See carbon building problem at high elevation: Update Webasto Gas Heater at High Elevation | RV With Tito DIY)

Secondly I'm glad I brought the kit from VanlifeOutfitter - there are so many moving parts and they put it all together. You can buy it here - Webasto Air Top EVO 40 – Gasoline Sprinter/Promaster Install Kit from VanlifeOutfitter

Thirdly, I'm glad I put it behind the driver seat instead of under the seat. The reason is I need a platform for the swivel seats as the feets are dangling and it is uncomfortable. Once I built the platform around the heater, I noticed how comfortable it was with my feet resting on the plaftorm. I plan to build a floor with hinges so I can store things in there as well.

For those who want to know where exactly to drill the hole, check out the pictures at the end of this blog article. I did the Webasto Surface Mounting Kit that was cut partially so it can install on top of van floor and bedrug installation underneath it.

You may be tempted to save money buying cheaper model or Russian/UK(Amazon) model or Chinese model but I've seen so many bad stories about it all. Don't go that route!

The install instructions are all over the place so best to go through these videos in order:
