i agree with those statements about the gas tank, battery, and the [email]f@#[/email] a#$--as i am a big boy myself--but the truck leans to the left even when the gas is low and i am out of the truck! i have not come up with a way of measuring the front end height properly to tell if it is a frame problem. the shocks and springs are the trd ones and relatively new--it had this problem before i switched them as well?
