Horsepower is horsepower. Two prime movers with the same HP will pull the same load up the same hill at the same speed. I don't care if it's gasoline, diesel, electricity, or steam powering them. Just let them operate at the speed they develope that power and ignore the sound they make.
Gasoline does loose some to diesel in thet more gear reduction can mean more parasitic losses and less HP delivered to the ground. The turbocharger also gives the diesel an advantage at higher elevations. the playing field may level if turbocharging becomes popular on larger displacement gasoline engines. A 5.0L ecoboost would be a good 3/4 and 1-ton truck engine for part time towing IMHO.
Sometimes the gasoline engine will win simply because the diesel can't spin fast enough to make the speed while delivering its extra torque to the ground.
Diesel will almost always win the fuel efficiency award. Whether or not it saves enough fuel to pay for itself has to be determined on a case by case basis.
Hands down one of the best posts in this section I have ever read.
Hat's off to you friend.
