Im kinda in the same boat as you. Im looking to trade our Trailblazer and my focus in on a f150 or f250 (4dr). the reason being, i need to get rid of a car and get something that is reliable. Plus we, in Texas, use trucks for alot of things. It will be a good all weather car and hauler.
in other words, get a V6 truck... that would take care of all your needs
