Yes, I am reading a post in the airstream forum about higher efficiency furnaces. Two are mentioned....
Excalibur 8500 IV Furnace, 30,000 BTU - Attwood. Has or had a design flaw with an electromechanical hum that is anoying.
Trumatic - German. Smaller very quiet.
This one apparently has the water condensate drain so may be really high efficiency.
