Perception is everything. If it "sounds" like it's effortless, it must not be working hard at all. To me, the groan of a diesel sounds more stressful than the subtle roar of a V8 gasser. But if it takes 250hp to pull 17000 lbs up a 5% grade at 60mph, that's what it takes and both engine will have to produce it. My last Cummins powered Ram had to run 2900rpm to produce 250hp. That was quite a racket.
I think you are right. Some people with an agenda to push will try to make you believe that the diesel is "effortlessly" pulling those weights and the gas engine is about to explode from overuse. I despise when people make these false claims on a forum where other people are seeking advice. Some people will actually believe the falsehoods and be very upset when they drop $70K on a new truck and realize that it was a lie.
Fact is, both trucks are working just as hard to produce the power. They are designed to safely make that power, just in different ways and at different rpms.
I had no problem with my gas engine pushing 3000 rpms to get up the mountain. I have no problem with my turbo spinning and creating 20 psi to get up the mountain. But to say one is more "effortless" than the other is laughable...
