It seems to me there is a big misconception about p/u trucks and suv's, and being total gas hog's.
No, i am not talking about gasoline truck/suv either because they get 7-18mpg at best, depending on size and towing as well. My diesel Fords get roughly 21-28mpg. That's including 2 p/u trucks (one of which has a lot of power upgrades that i race) and a suv with only loosing a few mpg towing getting about 20-22mpg.
However, i do know of quite a few 4 and 6 cylinder cars/ light suv, that don't even get better milage than i do!
