Propane or Charcoal : Seperate Tank or trailer Fed?

We use a small weber and charcoal for all of our BBQ'n. Since we are primarily weekend campers the process works great for us. If we were full timers, we probably wouldn't use the charcoal every dinner like we do now.

We do have an LPG tank that I bring out to the picnic table that I use with a stove that I can use with our cast iron frying pan for breakfast cookin.
