I'm not against higher RPM's or even the noise from a gasser. I'm more pro diesel because I want a relaxing tow with less input from me, the driver.
A gasser requires more input, that means pressing a little harder on the accelerator, letting the truck find the right gear, maintaining the right gear, down shifting as required, holding the gear as required. More effort to descend a steep grade.
A gasser requires more input. Now some may consider that extra input part of the fun and I get that. Sort of like why some enjoy driving a manual transmission.
Personally relaxing and enjoying the ride with little driver input is my idea of idea of a smooth trip.
The diesel takes all the work (driver input) out of the equation. Some may consider me a lazy driver because I want the truck to drive itself with out input from me, to some degree you are correct. That's why I paid more for a diesel performance.
