I was sitting here thinking about the price of diesel and that I have to fill up tommorow. At 20 mpg avarage and almost 4. 00 a gallon now why do I drive a diesel? A v8 powered truck gets 20 mpg, cost less to fill up, not sure what else. I know the Nissan, Toyota, Ford, Chevy and Dodge have 1/2 ton trucks that get 20 MPG on the freeway wich is where I spend most of my time. I don't tow much anymore and if I did a 1/2 ton would do it, just not near as well. I used to like the sound of the diesels, but that went away with the third gen trucks. I could easily trade my diesel for a nice used gasser, straight trade in some cases. Any reason why I shouldn't?
