That looks real good, don't really like the crockpot version, doesn't get the full flavor.
PS: Welcome to the forum.
Here is a crock pot recipe that will fool anyone. Cook your butt in the crock pot till tender, remove, slide out the bone and pull, Be sure to retain a fair amount of liquid.
You can do this now or wait till the next day or so.
Put your meat in a foil pan with some of the juice and place on the smoker with your favorite wood. Smoke at 225 º turning over the meat a few times for a couple or three hours.
That way if you don't have 10 -12 or more hours to spend you can do it in a couple.
I have done this a few times, because of time or weather problems.
