MetroMPG reminded us that the Crisis Fighter Pinto of CAR and DRIVER,1974, had a very low airdam and it helped with their MPG.
Also,graduate engineer Feysal Ahmed's Masters Thesis research showed a drag reduction for a pickup with a 3" clearance airdam,although he recommended it only for racing applications because of the demands of driveway ramp clearance 'n such.
Some members have used rubber belting for low airdams and it seems pretty indestructable.
Give it a go and keep a good logbook to see if she 'shows' on the computer or at the pump.
