I have a Carver; Bob Stevens has a Plat Cat--right, Bob?
(Carver is a predecessor of Propex.)

A very significant difference is that the Propex is forced
air with vented combustion, so no water vapor is discharged
into the passenger compartment.  Cat propane heaters
put the H2O and the CO2 in the passenger compartment.
I run my Carver with no window open or one very slightly.
With a cat heater you have to supply combustion air and
vent the water vapor.
