Define "Decent"? for what it sounds like you want a suburban may not be the best choice. I am not aware of a V6 version but some of the other guys here will know better. If milage is such a big concern you may want to look at newer E85 compatable Burbs, I think (2002 or newer) or maybe a mini van. Of all the strengths of the suburbans milage is not necessarily one of them. The diesel guys may disagree but I get 10 mpg with my 95 and very happy with it. But I don't use it just to haul kids around, without a requirement for towing or hauling gear of some sort there is probably a better fit for you with a more fuel efficient vehicle.
Please note that my comments are ONLY because you seem to have a very high priority on gas milage. If that were not your primary issue then the suburban is the perferct kid hauler.
