If you need a grill that functions as a smoker as well I would recommend the Big Green Egg. They are not cheap but the flavor and efficiency is fantastic. The lifetime warrenty is a nice perk as well. My favorite thing to grill on it so far is smoked pulled pork. Basically I do the following. Obviously there are more details to this with rubs and setting the chips for constant smoke etc. But heres the basics.
1. I set the temperature at 225 and throw the pork shoulder on at 8am before I go to work.
2. I check at noon (during my lunch break) to see if theres a temperature change (so far in the 5 times I've made this dish no adjustment was needed) and spray the outside with apple juice.
3. Check again at 4:30 and respray with juice.
4. At 6:30 I have delicious smoked pulled pork for supper while I was at the office for all day!
I love my egg and I use it year round in what most Americans would consider a harsh cold climate as I'm from St. John's Newfoundland.
