IIRC...Ram responded to TFL and said the truck handled the hill as designed...the software is designed to keep the engine from turning high RPM for long grades...basically they have a slow and steady approach to hill climbing.
This is what happens when people want long 100k miles warranties or life long warranties so they only have themselves to blame. The truck maker will stack the odds in their favor with computer nanny's to ensure there is no possible way they will be paying out during the warranty period or at least lower the chances of them paying out.
Constant high RPMs will damage an engine although not nearly as bad as that short period of time (10-15 minutes) that your engine oil takes to get to operating temp coming from a cold start(never rev your engine too high during this time). Will constant towing of a modern engine past 5,000 rpm on long grades make it have a catastrophic engine failure before 200k miles? I highly doubt it from all the engines I have tested as long as you change the fluids on the "severe" cycle and keep the engine from getting too hot. However, you better believe Ram will stack the odds in their favor especially if one little low cost program of the ECM can make their chances of paying out of pocket on a warranty decrease dramatically.
