The utility of a short bed quad cab pickup truck is just slightly better than if you took a reciprocating saw to the rear roof of a standard SUV.    

If you're going to get a pickup - go big or go home - get one with a long bed (if you really need to seat 4).    More realistic: get one with an extended cab (vs a quad cab).    Then you have the best of both worlds - some inside storage space (with jump seats for short rides) and a fairly decent sized bed - without being longer than a standard parking space.

Oh, and make sure you know how to drive it.   My neighbourhood has far too many urban cowboys driving massive pickups.   They drive down the center of the streets because they don't trust themselves not to hit the parked cars and and compound this by parking like total beginners - turning a two lane residential street into a narrow laneway.     And don't kid yourselves - their shiny pickups never end up hauling much more than groceries and some odds and ends to the cottage.
