Since you are looking for leather, that will eliminate the XE trim level, which wouldn't have the Big Tow mirrors. The easiest way to look for Big Tow is if it has the big "Big Tow" mirrors, which manually extend out and have the small convex mirror below the main mirror, has a transmission temperature guage on the dash, signified with a gear, and has the factory receiver hitch with 7 pin connector. While the receiver hitch and the big tow mirrors can be bought as a dealer accessory and installed later, the transmission temperature guage in the dash is exclusive to Big Tow only.
