Long Standing issue, but I figured I'd bring it up again. I'm sure this effects many users. On my 98 GMC K1500 the EPA figures the site uses are wrong. I suspect that the site is applying the standard cab figures to all models. Mine is an extended cab, and heavier than the standard cab. (and therefore has a lower EPA rating). I'm sure this probably extends to many years, and maybe all pickups listed in general.
