Bobby, I do potatoes and onions and garlic w/ seasonal in the smoker all the time. I usually cut up 5-6 potato's 2 onions a head of garlic and a chit load of butter and season all, then wrap in foil, toss in smoker and cook till soft. I would assume you could do the same for the potatoes and carrots. Usually I would count on at least 2-3 hours at 235 just start checking em, so it'd be OK while you're hunting. As for meat - wings are usually ready within this period of time, or maybe you can keep them a lil' longer.
