08 Limited = 3.31 gears, NO HD towing package, 18" wheels, reverse camera, power running boards. Built 9/12/08
08 Eddie Bauer = 3.31 gears, DOES have HD towing pkg, 20" wheels, NO reverse camera or power running boards. Built 8/25/07
If it were me I would go for the Limited because it has the newer redesigned heads that dont have the spark plug problems and it has just about everything except HD towing and 20's.
HTH
