thanks for the welcome, the gas mileage im getting now isnt so great anyways so gas mileage isnt so much of an issue., as of now I have a 2001 v10 f-350, it only has 39k miles on it, gets used everyday but pretty much just in the local area, when its used theres alot of weight in the bed. It well get run hard in the winter as well with the plow on it.
