Well. You did join a forum for the 2019+ 5th Gen RAM 1500 to ask a question about the 4th Gen 2500...lol
Not sure what you are considering the tow package.
All RAM 2500 trucks come standard with all towing equipment, hitch and trailer wiring...tow mirrors, trailer brake controller and the 5th Wheel setup are options.
And the standard mirrors are, well standard.
The question I have is why would you buy a truck without tow mirrors if you wanted them?
You could get the tow mirrors as either a stand alone item ir as part of the snow chief package.
Did you get the trailer brake controller?
As you can see nit everyone is a fan if the tow mirrors. And that would be why your truck didnt come with them.
We have a sister aite for all the generations of HeavyDuty RAM trucks.
