I don't have a choice but to drive the truck in my signature. The only other thing I have to drive is a 92 Chevy gasser that at it's best can only make about 13-14mpg. Two tanks ago I squeezed nearly 21 out of it, and even when I get on the throttle a good bit can make 19mpg. At current prices I'm saving about $70 every 600 miles by driving my diesel instead of the gasser. Sure, I could get better mileage on some other vehicle, but then I'd have payments and insurance, and I'd still probably end up driving the Ram since it's fun.
