In order to have any real load-hauling capability it has to have allot stiffer suspension in back, which makes it heavier.
it also has to have a stronger frame, unibody doesn't do well with out big ole stiffeners, which makes it heavier.
All that extra sheet metal and glass on the back end behind the rear axle affects handling, and make it heavier.

A pick-up truck makes so much more sense to me.
