 wood work (this is a westy remember).  make the vent and splice be able to
be
 closed to isolate if no passengers.  maybe put a 12volt fan in line to pull
more
 heat thru?  i would think duct work from home supply stores would work
 nicely.  anybody ever try this?  it would entail cutting a hole in the floor
 but you have to do that if you install an aux. heater, right?

look at a van w/ a BA6 gas heater, and you'll see what to do..
