This would work.  Actually my dream setup would be to cut a hole in the duct
work that is built into the body on the driver's side (behind that wooden
trim that supports the rear light over the cabinets) and then force the cool
air up to the front of the van through these already exsisting ducts (used
normally for fresh air on non-westies), through the doors, into the dash
somehow and out the front dash vents.  Then you could close the rear vents
tottally when no one is back there and you would probably get a good bit of
A/C air out of the front vents.  Still dreaming, but it could work!!!
