Yes, drive as many as you can. Definately not just one or two of each. As for fuel mileage, the single biggest factor in YOUR OWN PERSONAL MILEAGE is...........YOUR OWN PERSONAL FOOT.

A great thing about buying a few years used is that you find them with many aftermarket add-ons installed already and the value of the add-ons really doesn't affect the price. Things like running boards, push bars, bumpers, bedliners, tonoe covers, lights, etc.....
