I am going to pick up a couple of whole bone in hams. I can decide if i want to do them in the offset or the Drum. With the offset they will fit right in the cooking chamber but I will need to watch it closer. The drum should make the full burn, about 17hr approx, with out having to add any fuel. My problem is I will have to lower the rack in order to make it fit, thus getting it to close to the fire. I am thinking about setting an 18 in grate on top of the fire basket and adding a water pan, thus making a giant WSM. I have been wanting to try the water pan anyway but dont want to mess up a $$ ham. What would you do?
