According to KBB, there are three package discounts for the XLT: Convenience, Chrome & Tow Pkg Discount $1500, Convenience & Tow Pkg Discount $750, Work Solutions Pkg Discount $500. All three require the Tow Package. But look at it this way, by adding the Tow Package to the Convenience and Chrome Packages you are still saving $1125 over buying the cost of buying the Convenience and Chrome Packages separately.
