Sometimes we run all splits and sometimes we run charcoal with wood.
For those long cooks when we want to get some sleep we run a few hours with splits and which we burn in our charcoal basket. Later, we shift to charcoal so we can get some sleep.
We bought our basket from Jeff at XXL Baskets. here is the link.

We find that when the meat is wrapped in foil it doesn't make a difference if we burn all wood or charcoal.
