I noticed a very low airflow from the rear heating duct in my '75 center twin Argosy 26. Pulled the curbside twin out for a look-see. Found two 2-inch flexible duct pipes running from the back of that sheet metal heating duct and then down through the plywood floor to who knows where. The twin had been taken out before, and this could have been a later modification. I assume the ducts lead aft to keep the tanks from freezing, but I may be wrong. This trailer spent a lot of time in MN, and might have been so modified for that reason. Anyone else seen a setup like this? Was it stock? I'm going to disconnect the flex ducts and seal the holes with duct tape (so it can be reversed later). My tanks are winterized, and I don't use them, and want all the efficiency I can get from my suburban furnace, even if I do only use it for morning initial warm-ups. Thanks in advance for any help!
