Methane (natural gas is nearly pure methane) is a much lighter molecule than is propane  (molecular weight 16 vs. 58).  It would therefore have much higher pressure and require higher pressure storage and delivery equipment on the vehicle.  Not just the regulator, but the tank and valves as well must be different.  The stove and refrigerator burner would have to be refitted with appropriate orifices as well, for proper mixing with air.  Though home appliances that burn one or the other can be had, they can do so only if changes to the valves and orifices are made.  Without these changes, not only would the fuel not burn at the proper temperature and rate, but it would not be safe to use.
