I do think it is more females that don’t understand the difference between natural gas and propane, natural gas is very safe, it is light and wants to escape into the atmosphere, propane is the heavy gas that puddles and collects in low spaces.
Cooks prefer natural gas.
I took fishing trips for many years. The cabins had propane fuels tanks for the water heater, refrigerator and stove. We were always told to keep several windows cracked at all times since there were no ventilation vents of significance.
