I, too, am a relatively handy homeowner and father, and we are finally upgrading our Prius to a ...minivan!
The only thing I've come up with that we wouldn't be able to do with the minivan but with a truck would be fitting a refrigerator standing up. The load floor in a minivan is also a lot lower, making it much easier to load and unload stuff. Not to mention that you can comfortably haul people, too, which is most of the use.
Which problem is it that you have to own a truck for?
