If you remove the passenger van center duct work you will find that much
more air movement reaches the front seat area than before. The ceiling
duct-work slows down the airflow and reduces it in my opinion. Whether
the overall result is satisfactory is a separate question that will
depend on individual circumstances and tastes. Try it and see, if you
prefer it. More air, YES.

The Westy rear A/C is a different animal and there are 2 version. Those
with the tan interior are almost all a weaker single fan motor setup
that doesn't move as much air and that people are generally dissatisfied
with. Starting about 87 it was upgraded to the more powerful dual fan
motor setup that passenger vans above got starting with 86. This
coincided with the  addition to the rear ceiling in the Westy of a wide
flat duct that carries cool air forward to the edge of the poptop
opening closer to the front seats. All of the 87+ grey interior campers
with A/C got this improved setup as well as a few late tan 86 models. It
is not just the dual fan motors that make the difference, that later
system is better all around IMHO.
