In the last year, I've done a couple of pork shoulders and a handful of ribs on my big green egg (hickory based charcoal (Fogo) with some apple chunks added), using a variety of rubs - some homemade, some store bought. All done at < 250F, with no water, etc. I do use a vinegar based sauce for my pulled pork, and will baste the butt/ribs occasionally with it (only 1-2x for the ribs). I haven't done any foil wrapping when cooking them - they've come out fine. I have wrapped the butts in foil/towel and put in a cooler to rest for a couple of hours before pulling.
I've also smoked a bunch of chickens and did a 18lb turkey for Thanksgiving. That I brined for 3 days, loosely filled the cavity with onions, celery and apples (Granny Smith). I also put under the skin a mixture of butter and herbs (rosemary, tyme, sage) as well as on the outside. Smoked it at 275, took a little more than 3 hours - delicious.
