Just saw your post, I cook them all the time. Pretty straightforward for me. Just rub them up with a rub you like, put them on the kettle indirect at 250F and let them go until probe tender. It makes it in 2 to 3 hours depending on meat and temperature control.
I have also grilled them, I marinade them for 4 hours, then onto the grill, no rub necessary. I will glaze with some thinned BBQ sauce to finish.
Marinade can be really simple, something like a oil and vinegar salad dressing. Or make your own, like a light brine. I often will just throw a couple cups of water and 1/2 cup cider vinegar into a pot, bring up to a slow boil, add 5 or 6 cracked black peppercorns, 2 or 3 whole cloves, a bay leaf, couple tablespoons of salt and then let cool, or ice, add pork and let it sit for a few hours.
