Yes and No.
The 'hole' in a westy is at least double the size of the sunroof hole.
Furthermore, the sunroof busses have a thick rib that surrounds the hole and
gives rigidity, as well as a great deal of extra "stuff" up there (you even
loose 1.25'' of headroom inside as a result!~)

I was under the impression that that cross brace was the only real
strengthener on the westy, but it's been a while since i've cut up a westy
(but I have done several). Since that cross brace is in place on this westy
in question, I don't really see the big deal. The wooden bunks aren't really
secured to anything in any way that adds any strength, and at least at first
glance, that's all the appears to me to be missing.

I think i'd drive around like that without much hesitation, but further
investigation may be required.
