Interesting.  I guess they work fine for the years/installation that use two separate evaporator fans.  My '86 Westy has a single, dual shaft motor with twin squirrel cages.  Not the same creature at all, and the front blower is very different.  There are aftermarket universal motors for the earlier systems like mine, however, that will work with the same blower cages and housings..

 As some of you know I recently tore the rear closet, AC and

 rear heater, =
 but took it upon myself to tighten everything up back there

 a rear AC blower that had failed.� Ron from the Bus

 that the front blower would work with several modifications,
 splicing =
 the old connector and drilling two holes to mount it.�
 A salesperson =

 the enormity of the =

 it with a used part, and took a chance that the front blower
 would work. =
  Given that we had a camping trip planned last weekend, and
 a van in =

 an exact replacement for the rear AC blower.� There are

 Yep, this is the usage I experience with my HS2800, which
 makes sense as
 the efficiency is probably similar.� The duty cycle
 would be lower on the
 2800 of course.
 
 I certainly appreciate the heater, but the girlfriend
 absolutely loves it.

 Well, I think I made the first "fleece thermal barrier" a
 few years
 back.� Version two:
 http://jones.colorado.edu/VW/FleeceBarrier
 
 Such a slight layer makes a HUGE difference in the
 effectiveness of
 the Propex.� I wouldn't think of NOT using it if I
 thought I'd kick
 on the Propex in the morning.� I sleep in a warm bag
 and only turn
 on the furnace a while before getting up in the morning.
 
 Of course I don't use the fleece barrier if I have grandsons
 sleeping
 upstairs....� ;-)
 
 And just believe Karl's numbers on Propex propane use.�
 I wondered
 last year if my tank would ever empty running the Propex and
 the
 stove.� Feeling how little heat comes out the Propex
 exhaust indicates
 how efficient it is.
