Members  of the Seattle area,

I have a complete set of original Vanagon heater  that was used for the 
early vans.  
I am in the Seattle area and am  not going to ship it.  So it’s for local 
pick-up.  

This  heater works off the from the gas tank’s fuel, made of stainless 
steel and is  to be fitted to the underside of the van.  All the electricals and 
 fittings are with it.  The Bentley manual is a great help in knowing what  
to do with it.  
It is winter and this is the time to fit it to your  van and have hot air 
blown into your van while even if it’s standing, engine  not running.  
It would cost a fortune to buy it new, but I would let  it go to anyone who 
gives me a decent offer.
