  Hi, Lite all four burners on the cook stove. If they seem to burn 
cleanly, you probably have an OK regulator. It would then appear that 
the furnance needs cleaning. It would have to be removed from it's 
case and attended to. Make certain that the outside venting is clear. 
The fact that the furnace does run is a good sign. Good switches, 
circut board etc. Also watch for leaks between the two chambers. 
(cumbustion and heat exchanger). Leaks at those points can allow CO2 
fumes into the living space.Be sure to turn the gas off at both tanks 
and the electric power to the furnace before starting this work. Or 
you can take it to an RV dealer for the inspection and work. Need not 
be an AS dealer. Good luck.. Arnie
