You have 2 furnace's.
The FIRST top pic is the "rear" furnace and heat duct hoses that supply heat from the rear to the kitchen area. The 2nd pic from top shows the 2nd furnace outside exhaust and intake for the FRONT area of the RV. This heats the driver cockpit area and the area about 10 feet back from the drivers area. The 3rd pic down shows the outside rear furnace access and this furnace is NOT in the basement but on the floor next to the refer inside and the backside of the FIRST pic. Yes, at one time Tiffin did install a duct cover, on the last pic showing a duct hose coming out of the floor, but they usually just let the hose blow warm air because it was better to not have that duct blow straight up and hit the bottom of the couch. You have either 2 wall tstats for the furnace operation or you have the Dometic LCD wall 2 stat with ZONE's. Zone 1 and Zone 2. Zone 1 controls the front furnace and Zone 2 controls the rear main furnace. Doug
