One Maxxair fan over the bed treats us just fine (though we plan to add hole/vent in the floor for those days over 100).
Im sure you could create tons of airflow with a second fan and one pulling in while one vents out... but you're still pulling the hotter air from on top of the van (rather than the cooler shaded air down below), and far more importantly one two fans are installed the real estate left on the roof of a 144wb for solar is minimal at best.
