I wonder how hard it would be to pull the furnace and have it tested on a bench. That would factor out a lot of issues. Some RVs, one can just lift up a dinette seat and have full access to the furnace. Others take some work to get at them.
Barring a window or other hole open that would suck in air from near the furnace exhaust port on the outside, it either is a leak in the intake/exhaust line, or a cracked heat exchanger.
