Am I correct in understanding that the factory rv propane stoves in campers create less co because they of a two-stage regulator in the line between the tank and the stove as compared to if you used a portable camping stove inside the camper (with adequate ventilation)? I guess I am thinking that the flame of the stove is consuming oxygen and the flame is the same between the indoor and outdoor stoves, but this must not be the case. Could you explain why "outdoor" stoves and "indoor" stoves are designated as such? Is it because of the high pressure and low pressure regulator, because of different levels of producing co, or perhaps because of both of these conditions? I'm still considering installing a regulated indoor propane stove to my shell camper above the furnace and putting a T-connector between the furnace line and new stove, if I have the clearance under the counter on top of the furnace. Has anyone else done this? Do you have any pictures or advice? Thanks as usual.
