The hose in question is on the low pressure side of the furnace. A leak in it would mean the furnace is drawing air FROM where you are, and NOT blowing noxious fumes INTO the trailer. The high pressure side (burned propane) has no rubber parts in the way to where the gas exits outside. Search this forum long enough, and you will find I am not the first person to state this fact.
Tom Patterson used to, or still does, run a newsgroup where "Dr. Gerald" used to make great posts. He once described his recovery from near-death carbon monoxide poisoning. He did not have a carbon monoxide (CO) detector.
I have my original furnace. I saw surface cracks in the subject hose. I smeared high-temp RTV on the hose. I employ a calibrated CO monitor. I have yet to have a problem.
But you should replace your furnace if you feel the least bit uncomfortable with it.
The list is still alive and well. The sign up page is here: Vintage Airstream List Index Page
There are different members of that list and I find them to be quite valuable. BTW, I know that I am not the only one on Tom's List who is a contributer here.
