My Powerstroke Excursion gets better mph's than the 4runner you mention ever will. Comes stock with 500 lbs of torque, and very comfortable to drive around. If you want a truck that is less costly, you could easily get a f250 powerstroke that will get you around 20 on the highway and 15-18 around town, plenty of power, and if you buy one that is a couple years old you can save some bucks. I would think this setup would cost the same or less as a 4runner.

Email me if you want specifics, this is my third powerstroke and I love it.
