Ford Super Duty 6.2 Super Ike Gauntlet Pull

I don't pull grades at 5500 rpm, don't need to even pulling 10k. I pull 4-4500 up any grade I have encountered thus far and could go faster but don't. Regardless, I know the diesel pulls less rpm because it's designed to. And diesels pull really nice for sure! The Ford 6.2 did great, I have the gm 6.0 and love it. Gas engines are doing much better and will improve no doubt. I could have bought a diesel a few years back, didn't need to, don't want to. Nothing wrong with owning one, but I just don't want to deal with the added expense of any breakdown and emissions related issues. Yes I wish to see the ford pull a cargo trailer or something similar just like the Chevy truck did a few years ago and did it around 10 min if I can recall. Hopefully they can perform that test and show what to expect pulling a camper.
