I'm renovating the rear area of my 77 Eleganza and noticed the furnace supply duct that runs around the drivers side of the coach, across the back, and then up to the bathroom and register under the 'bed'.

However, no air is moving through the duct. On the front (toward the driver) of the furnace are two outlets, a 4" that goes to the register under the DAVO, and a 2" that was obviously capped of by a PO. I do not see any of the 2" flexible supply line but ASSUME that this capped off area is where the hose is SUPPOSED to connect??? Seems odd that the supply line would come off the 'wrong' side. Is there another connection hidden under the cabinets? My shop manuals (75-76 maintenance and 77-78 Supplement) do not describe the duct runs.

I also assume there is a 'TEE' in back of the bathroom (Propane tank box) to feed both the bathroom vent AND the register under the bed area (I assume this once was set up for rear facing settee's

Anyone got any insight for me? I'd just as soon address this area now while I've got all the bed framing off.
