HOW TO INSTALL THE NEW ESPAR AS3 D2L Diesel Heater

Having trouble fitting your diesel heater under the passenger seat in your Sprinter? We had the same problem and couldn’t find much information. That’s why we made this video. Check out our install of the new Espar AS3 D2L Diesel Heater. We discuss our design thinking, select placement for the installation, and utilize a turret to mount the heater.

This video is for you if you need help determining where to place your heater in your van. Likewise, if you're curious about the new AS3 D2L, we're here to tell you it's a worthy investment if you're chasing pow and winter camping at high elevation in your rig. This heater is awesome!
