i cant speak for the overseas markets and possible packages, but the tow package is more of a dealer add on, including trailer hitch and wiring but doesnt go as far as beefier brakes or better gears or any of the like.
I was curious. If this is true about the "tow package", then why does the manual say that you can tow 2000 more pounds if you have the tow package? I am not contradicting you, I am just trying to understand this about my 80.
