Partial heat in Fifth Wheel.....

[unclecooper]

Have heat in first two thirds of rv but none in the rear. Can feel cool air very,very slightly coming out of vents back there in half bath and bunk room. Have had this since new but (2 years old) but just dealt with it...used a space heater. Have had 2 summers to start looking but.........Anyway, I sent a camera down those vents but they did not get far, could not get it around the bends. In my basement, I could partially see the vents coming from the furnace through the water closet but then they disappear into the water line, wire jungle! Trying to get more access there but not finding any yet. Can I see the ducts by taking down the underbelly cover? Seems kind of low...it is like a plastic,rubber kind of material...not sure if one piece or sections...don't remember. There are bolts (not rivets)so that would help. I had dropped a very small portion last year to see what I could see....there is a thin clear plastic film under there and I did not want to tear it so I stopped. Any suggestions? Should have jumped on this right away! Guessing a duct came off or was never attached?
It is a 2022 East To West Ahara 378BH-OK

Do you mean a 2022 or 2020 since East to West wasn't around in 2002?

No idea how East to Wests are built. On my Flagstaff, on a trip down to Florida, the front section of my underbelly peeled back and I had to totally remove it. The heat ducts were all thin foil/plastic flex duct work. It was so loose that once the underbelly was gone, it was dragging on the ground. To get the best airflow, this stuff is supposed to be stretched tight. While the underbelly was off, I replace 99% of the duct work with mostly rigid aluminum and one short length of heavy flex aluminum. I had one short section that ran between my black tank and the frame that I had to use the flimsy foil flex stuff. On my longest duct run, I had much better heat after the conversion. Side benefit, I doubt mice will ever chew holes in it.
