The beauty of that $4,000 Kimberley stove is that it requires NO ventilation from inside the RV as it uses OUTSIDE air for combustion.
The stove draws NO air from inside the RV to facilitate combustion. The air intake into the stove comes through a 2-inch hole drilled through the floor of the RV to the outside air through which a tube is snaked through that hole to several inches below the floor up into the bottom of the stove itself. All installed with proper sealants, etc.
The stove has it's OUTSIDE air intake at the bottom of the stove via a tube placed into the floor hole to the outside. Thus, there is no need to be concerned about CO2 poisoning, etc. A completely closed system. Gotta love it!
If the intake hole is somehow blocked by debris,etc., combustion ceases and the fire goes out. like virtually immediately.
(Pssst...Keep a CO2 detector onboard anyway) ;)
A couple of youtube videos show how it's installed and used in an RV and in a sailboat.
