On my '05, I have a class 4 hitch and the needed relays already installed. I also have the gears by virtue of the OR package. (same gears, correct?) The battery's also been changed.loufish said:1. tow mirrors
2. Lower rear gear
3. Trans temp gauge
4. Factory install class IV hitch and all needed relays
5. Larger capacity battery...
The only things that seem to be missing are the mirrors and the temp guage.
So can I safely tow more than the non-BT limit of 6400#?
