O.K i've sold my westy, and now i'm selling the heater too.  it's a
"Platinum Cat" 12 Volt DC Power VENTED Catalytic Heater, it's made in
the U.S.A. by Thermal Systems Inc. The model number 6P12A. It's rated
at 5200 BTU. This heater was built for use in motorhomes and trailers
and is extremely efficient. It has a built in blower and includes the
thermostat controls.  i also have a gas regulator and hose so you can
just screw it into a barbeque propane tank.  i had it hanging from
rings that i installed near the visors above the windshield and it
heated the whole van.

$350/obo + actual shipping cost
