Well since you asked...

I use a rub that I make and put it on the ribs usually the night before cooking and let it sit in the fridge wrapped in foil until time for cooking.

Get the smoker to temp of 225-250 and place the ribs on. The key is indirect heat with this. The ribs are cooking for 3 hours then I wrap them in foil with the shiney side inside and cook for 2 hours then unwrap and apply sauce of choice (I do home made) and let cook for another hour.

I tend to put some apple juice in a can and place it inside the smoker so there is extra moisture and flavor but it's your choice on that.

Should give you ribs that fall apart nicely and taste awesome.
