This Heater is new in the box. Never took it out. I bought it about 10 years ago for my Syncro Westy but never got around installing it. Now I have a new van that already has a heater and no longer need it. Here's some info about this heater from the manufacturer: http://ventedcatheater.com/2.html And here's some info from the Samba Forums: https://www.thesamba.com/vw/forum/viewtopic.php?t=3783...
