A sunroof is an excellent addition to the Vanagon.  I put one in my
Westy, and in a standard Vanagon it is even easier.  See
http://pws.prserv.net/synergy/Vanagon/Sunroof.htm  for instructions, and
you won't need the optional trim ring for your installation since you
don't have the wood panel headliner.
