I don't do much marinading of any sort but when I do, I just use plain old Itatian Salad Dressing over night on my chicken quarters and then smoke them outside in the smoker. The leftover liquid I'll pour over the potatoes and the chicken as they're smoked. I know boring but it's just me these days and I don't need anything fancy. Plus the Italian Salad Dressing has all sorts of spices already in it and my chicken comes out very tasty and moist and the baked/smoked potatoes also have that flavor so you almost don't even need to add anything else to them.
