It’s amazing to me how people say “what does the owners manual say” when it comes to maint. but when it comes to tow ratings that goes out the window and people say “use 80% of the max”! Well which is it. If the manuf knows best then why not tow the max weight?
Just because the manuf gives a schedule of service does not mean you can’t do it earlier!
I am a firm believer in preventive maintenance. You'll always find me on the side for annual bearing repacking with brake adjustments. I always change fluids early and don't trust the dealer or others to do the work.
However, he has a 2500, tows a 6000# trailer at 60 mph. That is not severe service by any stretch of the imagine and replacing the trans fluid now is simply a money maker for the dealer.
