David,

I had a 90 Multivan that had two rear facing jumpseats. They did not bolt to
the floor. There were two recessed holes in the floor that the legs fit in.
The back of the seat locked on to a bracket that was mounted on the back of
the front seat pedestal. The bracket is what holds the seat in place and
when locked the legs of the jumpseat cannot come out of the receiving holes
in the floor. I am not sure if the camper floor has the receiving holes in
it. You would have to pick up the carpet area and see what is underneath.
