My furnace has a lot of exhaust smell when running. It's really stinky. I don't dare run it.
It's build date is 1999, and I doubt if it has 100 hours on it.
The heat exchanger looks like new, no visible cracks or holes
I pulled it out and check the connection to the exhaust pipe that goes through the side of the coach.
The furnace pipe just slides into the exhaust pipe. It seems like there should be more of a seal there. No clamps, no gasket?
Is this right?

yes, that's the way it fits. if the furnace hasn't run in a long time it will emit an odor for a few minutes as it burns off any dust and rust on the plenum surfaces.
if you have the unit out you might want to do a pressure test on the plenum to be sure you don't have a hole in it. fit a vacuum cleaner so it blows out and hook the host to the outlet and block the inlet. look for air coming out somewhere around the plenum.

Well I pulled the entire unit out and tor it down to remove the heat exchanger. I found a bunch of burnt jap beetles, and a good size chunk of a mud dauber nest and dirt. I shook a few rocks through the inside and it seems to be clean now.
I also removed the bug screen as Suburban says not to use them.
It seems better so far, not perfect tho.
I'll run it for a while and see if I can burn the smell off.

Just about any furnace that was off for the season has an objectionable smell the first few times it is in operation till the accumulated dust burns off the heat exchanger. I used to get a number of service calls the beginning of the heating season for just that reason.

If you are sure its combustion gas and you are satisfied the the exhaust outlet pipe is functioning properly really look close at the heat exchanger for cracks or a separation. It usually happens near the burner rack if your furnace is that type. Be careful carbon monoxide is lethal. I have a battery operated carbon monoxide detector mounted just above my rear bed too be safe.

Although combustion exhaust can and does have smellable
elements, if you were getting dizzy, you were most likely on
the verge of carbon monoxide poisoning. CO has no odor, but
dizziness is a symptom.
Jesus, man, please don't re-install that thing in your coach
or operate it in the presence of a living creature until you
either get it fixed by someone who knows what to do, and you
have an operating CO detector installed in the space. Better
yet, dump it and get a new one, AND install a CO detector.
We don't want to see a headline like:
"RV Owner And Family Die From CO Poisoning"
