Camping Stove & Gas BBQ. Can I use Butane or Propane? - camping gas regulator

We are equipped with a kitchen, which is recommended for use with caution, and installed a 28MB supported butane regulator. We also bought a gas grill is equipped with 37MB of propane reg statements use propane to the state.
We want to have only one bottle with us, and my question is: Will we be OK to change the Governor's Barbecue and the use of butane to? My mother has a gas grill butane and understand that there is not much difference between the gases other than propane is better for the winter, so it should not go?
