Propane or Charcoal : Seperate Tank or trailer Fed?

I have a grill and a Coleman stove that I converted to LP gas, I carry a separate bottle of LP and a long hose to use for these two. I usually set them up side by side on a picnic or metal folding table as I like to do most of my cooking outside (weather permitting) I also carry a tripod and cast aluminum pots for "over the fire cooking"
