I am still shopping for a good used truck. I am now checking fuel mileage; there are sites where people report fuel mileage from everyday use and not just what the manufacture states. I was looking at a really nice used F150 but the highway mileage was 19 (V8) and I was thinking of also using the truck as a daily driver. I am now thinking V6 over the V8 engines. If fuel goes to $4.00/gallon here that will be a game changer in what sort of truck I get. I hate not getting that truck, it was sharp looking, clean, interior was like new; but the fuel mileage? It sold so doesn't matter now.
