I recently replaced the latches on one compartment of my 97 Fleetwood Bounder
You have (2) options and are not going to like either of them, and you will need to remove the trim on both ends, (all 8 screws) as you know, the latches are bolted to the trim, and the trim Ãs glued to the inside and outside faces, you need to slide a sharp edge between trim and the inside outside face sheets to loosened them
#1 Cut holes on the inside/backside of the door over the latches to enable you to disconnect the rods that move the latches, unscrew and remove trim, (cut glue) replace the latches, reassemble, this is the easy method,
#2 is unscrew all the trim, remove top and bottom long trim, and remove the inside / backside cover, Which is also glued to the Styrofoam filter
Remove door from RV for either method
I chose method #1, then covered the square holes with Foil Tape, nobody but me sees the backside of the door unless i leave it open
