Here are some ribs I did on my weber 22 kettle. I did the loaf pan with apple juice over the side with the coals and just dropped wet applewood chips in about a handful every hour that kept a nice easy smoke going be sure to use a small amount of coals and keep adding you dont want to get over about 15 -20 in there at any one time or else it will be hard to control the temps. I smoked them on there for three hours and then went to the (Texas Crutch Method) much like foiling only you use a big disposable aluminum pan like for a buffet fill it with 12-16 oz of your favorite liquid and you put all ribs in there on top of a rack to keep above liquid, foil top throw on gas grill at about 325 for 1 hour and it will steam ribs so the fall off the bone makes them so juicy and tender, then back on weber for finishing sauce.
This will shrink them up like pic on right, pic on left is before (texas crutch)
Hope this helps.
