Thanks for the feedback guys.  We are definitely going to buy used rather than new ... new anything are just far too expensive these days.  Good to know on the engine sizes ... if we go this way we'll make sure that we get the larger one.  Having a small truck bed is one of the main things we want in a new TV ... miss being able to use one from the days I had a pickup, and an SUV gets very messy to clean when having to load up the back with stuff.  Not worried about the gas mileage as that is what my Veracruz gets now when towing, and we are going to make a change so that the new rig will be our "secondary" vehicle used mainly for towing and p/u type errands rather than being our primary one like the Veracruz is now.

We've made the decision to get a new (newer used) TV this fall and am looking at the 4-door types of pickup with a smaller bed and larger towing capacity in anticipation of some much longer & harder camping trips coming up next year.  Besides the typical 4-door versions of the regular pickups, one in particular that we see falling into our criteria is the Ford Explorer Sport Trac, which is a short-bed version of the Explorer.
