My last 5er was an older Kit Roadranger that I pulled with a 2000 Ford F250 7.3 diesel. It was plenty of truck for the trailer. I used a tuner to change it's shift patterns for towing which made all the difference in the world when climbing hills. The tranny was built to heavy duty spec but was still only a 4 speed tranny. Changing shift patterns dramatically helped to hold the RPM's up so downshifting was minimized which improved the entire experience.
My current 2012 RAM diesel has a 6 speed tranny and I'm noticing much less drop in RPM's. I do have a tuner but the difference from Stock to Tow is minimal compared to the Ford.
The more speeds they build into the tranny, the less alteration seems to be needed...if any at all.

And the new gen GMC/Chevys will have a 10-speed Allison, should be interesting haha
