I'm possibly selling my 04 to a friend and buying an 06-08 f150. I love my lifted truck but the poor gas mileage is always a pain and parking next year at Fsu will be an issue in the garages. Do yall with 06+ have issues with the knocking ticking or rattling? I hate my ticking and just want a quiet truck from the front and a nice growl from the back after I get done with the exhaust. Any help is highly appreciated.
