I am considering finding and installing a jump seat (behind the front
passenger seat) in my '91 GL Camper.  Has anyone done this?  This model
has no provision on the floor for the seat.  My understanding is that it
bolts to the pedestal of the front passenger seat, but needs to have
some provision made for bolting it to the floor also.  I don't want to
buy the seat, and then learn that it is not possible or practical to
install it so that it will be safe.

In particular, if anyone reasonably near to me (I live in central
Oklahoma) has such an installation, I'd like to see it and go from
there, but any and all advice would be welcome as potentially helpful.

Thanks, David McNeely
