There is your floor plan or some variation of it. I have not installed a TV on a RV wall with a pocket door. My assumption is the RV wall is much less rigid than a S&B interior pocket door wall which I have installed a TV on. The concern is not necesarily the weight but the fasteners for the TV mount poking through and stoping the door inside the wall.
You would need to build out the thickness of the wall probably with plywood. 3/4 to give it depth and rigity. Fasten the plywood with adhesive and conventional fasteners then connect the TV mount to the plywood. (no articulating arms, just a plain flat wall mount) Good news is the plywood should make it stick out enough so you can put up a 32".
These are of course all just assumptions as I have never been in a SP293 nor have I seen any picutres!
