I saw that too. Then I scrolled down and saw that all models already get those same brakes as standard. Confused why they list it as a component under the max tow package if all models already get it standard.
The $250 trailer tow package provides:
240 amp alternator
Heavy duty cooling
Trailer hitch zoom
Class 4 hitch
So the extra $745 for the max tow provides:
4.10 gears
Heavy duty wide axles
If you want to regear to 4.56 or 4.88 anyway, then you are essentially paying $745 for 1.5” wider axles...
