I don’t recommend doing this. But in a pinch 8200lbs 740 mile trip with the worst climb 5 mile 4-6% varying grades in 80-90 degree temps. 2000-2200 rpm is the best for heat management and forward progress.
Flat towing in 100-103 temps same 2000-2100 6-7th gear occasionally 8th on down hill ish runs works best.
My truck is intact never cooked but we did stop for a couple of cool downs when we hit 219 trans temp with more climb left ahead of us in hot 90+ outside temps.
Coolant temp if it warms up past center it will pop up actual temp next to the dummy gauge 228 is the trigger point, once it drops below 228 it reverts to the dummy gauge. Super quick to drop coolant temp by slowing down, dropping RPMs to the 2000-2100 range lighter throttle, run heater etc. Like a minute or less to drop temp if you take action right when it spikes its a quick easy effort to drop temp.
In case your wondering I had 2.5inch squat. Truck was empty except two adults and 60lbs of gear. Trailer is electric / Hydraulic 4 disc brakes serious brake power. Lots of hauling experience it wasn’t as good as a F250 but can get the job done if your cautious and know what your doing.
Fully permitted in three states not hassled by any highway patrol entire trip.
Mileage ran between 9.4mpg and 7.4mpg.
Higher RPMs 2500-3000 most definitely generate far more heat. Likely related to turbo heat under harder throttle.
Power? Easily accelerated to highway speeds even with short rampand steep climb, power is definitely NOT an issue its cooling you run out of quickly especially 2500+ rpm.
I can see people easily cooking the 3.5 and 10spd because of its huge torque and power under heavy load without paying attention to temps
