So far as I know, all newer model vehicles push heat and a/c to the back seat, but I'm not sure whether this one will be via moveable vents or some kind of system venting from under the front seats. I can't remember the exact measurements of the back seat, but it does seat 5, and the dimensions are a (very) tiny bit larger than the rear seat on the Ranger.
