Here on our site is the standard manual on the 8000 series. The newer one is a 8012-II
If yours does not have the -II it might be the older 8012. I'm not close enough to these older ones to know the difference between the 8012 & the 8012-II. The exhaust assembly might interchange.
However on page 5 it has a part call out. It sounded like what you were talking about was an exhaust tube assembly, part 29 on the diagram.
You mentioned a "flue smell" in the camper. Can you elaborate some more on this? Did it smell like burnt gas fumes or hot dust burning off?
There is a combustion chamber (heat exchanger) that is supposed to separate the inside from the outside. The furnace draws in outside air into the flame side of the heat exchanger. When the flame starts the blower draws the flame and heat through the outside part of the heat exchanger and heat/fumes passes through the sealed chamber and exhaust outside. The flame heats steel chamber and then on the inside, air inside the camper is blown over the hot steel and heat comes out the front of the furnace inside the camper. So any gas fumes should blow outside. The inside and outside air is separated on purpose.
If the gas fumes start coming inside that is not good. It might be a rusted through heat exchanger ( a hole in it) or the exhaust tube like you were mentioning leaking back.
Dust can be inside the unit from not being used over time and when heated it gives off a smell but it is a different smell then gas fumes.
Once you figure out what parts you need, there are some places online to buy from or local RV dealers. First is to figure out what you need.
They still sell the entire new furnace, but it will be the 8012-II.
Hope this helps
