I have a Windsport 34R. My water pump is located in the far rear corner, driver side under the "nightstand" adjacent to the bed. The front of the cabinet has a louver type front (4 screws). I would also look under the bed. You'll have to lift the mattress and unscrew the plywood bed deck. Under mine is all sorts of good stuff including the main drain for the fresh water tank.
Hope this helps
