You are supposed to run the range hood fan to outside venting while using the propane stove top. There is also a 12v light in the range hood so you can see what you are doing. The stove top itself does not need 12v.
"Supposed to" is perhaps a bit strong; "probably would want to" seems about right to me. In terms of water vapor, combustion fumes, etc. it can be effective enough to use window vents and/or ceiling vents.
My RV's range hood doesn't even vent to the outside; the fan sucks air through the little metal grease filter in the middle of the hood and recirculates it out to the left and right, still under the hood. It's a great useless noisemaker. The light is nice, though.
