My '81 7-passenger = no seal or vent.  We aren't supposed to
be sleeping in them.

I have seen Westys with a second battery with only carpet or
less covering them.  I have a piece of an old masonite sign cut
to fit and screwed down with 4 self-tapping screws.  The carpet
covers it.  It is a stock Group 41, so fits perfectly, including
for height.
