We are using a Magic Chef stove similar in size to what 01marc describes. I pulled it from a defunct 5th wheel about ten years ago. It has 4 burners and an oven and runs on the same propane regulator as the space heater and the on demand water heater. Wifey is able to bake PERFECT apple pies in it though I don't know about 7 pound turkeys. I may be wrong but I think all the RV propane appliances use the same regulated pressures. The stove does vent in the bus but I have fume hood above that vents to the outside.
