If you tow a lot it is worth it for the HD cooling options. it looks like the axle ratio is 3.23 across the board for everything. It also comes with a trailer brake controller which could come in handy.Is it worth it?
I know on some GMC models upgraded trailering means bigger axles, lockers, etc.......doesn't seem to get any of that does it??
This is on a Yukon Denali 2021.
