Michael on my '93 (now Jon's coach) I had installed shut off valves on the heater under the bed. Don't remember which system that was served by but you are right that 1 set goes to the marine water heater and the other to the front dash. I would think the under bed heater would be the same as the water heater since the dash A/C control activates the booster pump.
