Optimal setting or not I suspect Mr Truck had done the best the Ram was capable of.
At 60 mph which is what they decided to go down the hill (I suspect the speed limit) The Ram will be turning about 2600 rpm in 4th gear. It appears from what I saw in the video 4th gear was the gear used when the truck was going 60 mph.
Had Mr Truck dropped a gear as everyone thinks he should have that would bring the rpms up to about 3483. I believe that is well beyond red line for the 6.7 Cummins. I suspect with the computers used in the engines and transmissions the Ram will not allow 3rd gear operation at 60 mph.
Perhaps Cummins12V98 can verify what rpm the Ram would turn in 4th gear at 60 mph. There is a possibility my math is wrong.
