Rear Window on 1984 PT40WL

[pt40wl1]

Does anybody have any reason for the rear window and metal cover on
the rear of the '84 PT40WL???

I am doing a complete rejuvination on my bird and am considering
replacing the rear window and cover with some new 16 gauge smooth
galvanived steel. This would save some weight as well as provide
better insulation on the rear. My bus is the rear bedroom model and
the rear window is not usable from the inside due to closet space and
air conditioning equipment in the rear of the bus.

I think it is a hold-over from the commercial bus design and serves no
useful purpose on this model. What do you folks think???
