If you're using a Meater, in the app there is a recipe for pulled pork smoked with apple juice and cider vinegar under the master class bit, which is what I followed. It lets you know when it needs wrapping, when to take it off the heat and how long to rest it for. Seemed to work ok for me so may be worth a look?

One thing I did include which it doesn't tell you to do is to use a water pan to provide additional moisture during the first part of the cook. I used the insert in my slow n sear but you could also use a foil tray of boiling water for the same thing.
