I just traded in the F150 for a Subaru Impreza wagon. Still have AWD but no clearance. I am getting 28 per gallon and at 6' 190 lbs am not too cramped. Still miss that truck, though -- just a little less when I blow by all those $3.60 per gallon pumps. Hopefully the savings will translate to affording more trips with the pups.
But the bigger question is how do you fit all your gear (kennels, coolers etc.) into a Subaru?
