RAM EcoDiesel a Flop for Towing

Regardless of the brand I think a truck should be able to tow its tow rating doing at least the speed limit of any US highway even up hill or it should lower its tow rating.

Would you apply this logic to commercial trucks as well? I mean, why not? They do many more miles than RV towing trucks do. I imagine we would have to start equipping commercial trucks with dual engines, or maybe even turbine drives, to be able to pull legal weights (105,000 pounds in most western states) up 7% grades which are also common out here. Or maybe they should lower truck weight limits so we can have 2-3x the trucks on the road, just so some cars aren't momentarily inconvenienced.
