The trailer we are pulling last time I weighed it was 15901lbs and yes I pulling it with a gasser and just like all motors it has power lose at altitude. Newer gas motors adjust to the higher elevations on the fly unlike older models. But you can't run diesel gears in them, you have to gear them so they run in their power band when pulling grades, but when we are running down the interstate I can still run in 6th gear at 2K rpm at 65 mph. My not sure about the other brands but Fords 6.2 with the 6 speed and 4.30 gears is a very capable pulling platform.

If you want to give your truck a test take hwy 191 south of 80 in Wyoming to Flaming Gorge Lake in Utah. On our last trip we were from sea level to 10K feet and it was a pleasure to drive.

You are preaching to the choir Denny - in my opinion.

I am running the 6.2 with 4.30's in an F 250 towing 11.5K fifth wheel. I switched to gas.

You just have to relax when you see another diesel thread spooling up. :W
