I always lock out 6th gear on my Ram while towing. The Asin transmission tends to hunt bad, especially between 5th and 6th. I've also found cruise control costs me almost 2 miles to the gallon while towing so I turn it off often and it allows a fair bit of speed variation in rolling hills. The gear ratio in the SRW's is fairly high, which in my opinion works fairly good as a compromise for when you're running empty at 80ish MPH on the freeway unload in 6th, but still have 5 useable gears for towing. I'm not sure where the claims of seven up steep hills comes from. Mine drops down into 3rd pulling hard fairly often, as did my 2011 2500 with regular output engine towing a trailer that was only 8k. Most freeway pulls you can keep freeway speeds as they only get up around 6 or 7 percent grade most of the time. Mountain highways often get much steeper.

With my 2014 Ram with just over 13k fifth wheel I can pull Daniels at the speed limit 60 mph in fourth gear, have never yet seen third gear on any grade yet that would allow me to go at least 50 mph, and that includes the hill out of Ashton Idaho into Island Park
FYI to the OP my 99 7.3 with a bunch of mods would pull the same hills mentioned above with the same fifth wheel down in second gear at 30-35 mph compared to the Ram at 60 mph in fourth gear. Yes something is wrong ,your driving or the truck
