I am carrying my medium, large too heavy to be putting in my Explorer, to do a butt cook. My question; What arrangement do some people use and what size butts? I have already bought a 2 pack from Sam's that weighs 16#s. That is what I normally cook on my large. I just can't see how to get 2 that size on the medium. Any suggestions would be appreciated. Maybe just get a couple of smaller butts?
