Interesting points. I lean toward the long bed for practicality, but I am not sure I want to be unable to use some parking garages and have to take up 2 parking spaces. those are issues to me. I don't mind walking a little farther when parking in a store parking lot. I do that anyway, but sometimes there is just no place to park and you to park wherever there is a spot available.
Is it true that you really need 2 spaces and that you can't park in some parking garages? I have to fly for work so that could be an issue for me.
My concern with cargo space is more for when towing when you lose a good portion of your bed.
