I wonder why mine's not using the higher gears while towing, maybe a defect in the trans? When towing on a flat, I use electronic range select to drop down to 3rd, and watch the rpm needle. there is a drop from 3 to 4, and sometimes from 4 to 5, but never anything from 5 to off, telling me the trans isn't shifting any higher.
Maybe the hemi doesn't have enough power to use those higher gears towing my particular trailer?
When traveling flat roads, in tow/haul mode at 'highway' speed.. if you hit the - button on the gear selector the current gear should display somewhere on the dash. At least that's how it works on my 2015, this is the only way I can veify what gear I'm in.
You don't say what you're towing, what gear ratio you have or the like. In my setup the truck uses top gear often, however I've got 3.93 gearing and we're hauling maybe 3k with the TT and truck bed contents.. less than 1/3rd capacity.
