Long time reader first time poster. Recently purchased the truck in my sig. and really enjoy it. It was used with about 12k miles. The ride home netted 20.5 mpg @ 70 to 75 mph hand calculated. All my mods will be focused on mpg and longevity more than performance. However that being said I do like performance. This truck will be our 5th wheel tow rig and my project car (800 HP pump gas 72 Nova) tow vehicle. I am sure I am not going to be as hardcore as some here but I do respect the amount of time and effort it takes to learn the ins and outs to make thses trucks perform. I really like reading lots of the post for all the small tips and tricks that most of us at home guys can do. I do all my own work as I was a heavy equip. mech. for 12years. My car is on hold for now so I like tinkering with the truck. Again thanks for all the expert advise and tips.
