It's understood that gas engines make their horsepower at higher RPM's, but it's the way they are designed since they don't generate enough torque to carry the really heavy loads. But after, say, 100K miles of high revving, max load on that gas V-8, you might not want to own it. Not saying they won't live that long or won't get the job done, but the high RPM's take a toll after a while. But if you only put a few thousand hard miles a year on a gasser it shouldn't be an issue. I have towed with both and I prefer to move the loads with that low RPM torque. I have gotten many trouble free, hundreds of thousands of miles with diesels, but I do love the sound of that LS6 in my CTS V revving to 6000 RPM's as I row through the gears on the Tremec T56 6 speed!
