Love my MB propane/charcoal. I've searched this forum for mods and made some improvements. Currently I am using the stock chip pan with lump charcoal and I hammered down the vents to stop flare ups, additionally I lined the water pan with foil and added some playground sand and foil on top with a smoker chip pan for flavored chips in the middle. I added a disposable roasting pan for water but I sacrifice a shelf. I've had fun smoking ribs, brisket, salmon and pork butt. You definitely save on fuel because once the pan gets hot enough and the lump charcoal starts to burn hot and you can use them for heat and smoke,just add more from time to time. One last thing I should mention, when I need the smoker to get hotter with the propane running I found that lifting up the pan and putting one foot on the protruding bolts on the bottom allows more flame and the temp rises fast.
