I've done it and you're right: It is a lot of work.
Got the full pig from local butcher 106 lbs of him. Rented a horizontal smoke from the Redstone Arsenal MWR. Started smoking him around 10 PM at night, stayed up all night with it. I used red and white oak, well seasoned, that was put into 5 gallon buckets with water to make the smoke. Used a temp gauge to keep it in the smoking temp range vs. cooking vs. too cool.
I used a dry rub from Texas BBQ (Texasbbq.com) pretty good stuff. And no, I didn't drink any beer until the next day, there's no way I could have stayed up all night.
I also smoked beef BBQ ribs (Fred Flintstone ribs) and chicken. Had about 35 people over the next day, ate like a bunch of pigs we did.
Got pics, I should store them somewhere so you can see them, let me work on that. Got questions, postem up!
Good luck.
