100 lbs boar or sow is fine. I do a whole hog BBQ,-- INDIRECT heat , low and slow, maybe 200-225 degrees for about 12(plus) hours. Pull or chop, season with salt,pepper,sugar and apple cider vinegar for an Eastern Carolina style feast.
For smaller roasts, sear and smoke for about 2 hours and wrap in foil and finish at low heat (200) for 10-12 hours in the oven. Should pull nicely.
For big pigs, get it to a good meat cutter for sausage. (save the straps)
If you screw up then go shoot another one.
