Is there a Diesel or Gas break point?

Other than at 11000 ft (one road in the whole of the North American Continent), I have never seen, or heard of the 6.4L Hemi acting the way it does on the Ike Gauntlet test at high altitude.

I have towed 12k (GCW was scaled at 21k) with mine all over the Canadian Rockies on all the grades there (6 to 7%, some near Radium at 11%) and never been down to 20 or 30 mph. There was only one time that I experienced personally that I couldn't accelerate when I wanted to. Times have changed. The newest crop of modern gassers have plenty of power.

In fact, my 2014 Ram 2500 gasser had:
- More payload
- Higher GAWRs *front and rear
- Higher max tow rating (by over 2000#)
- Higher GCWR by 2000#
Than my 2007 3500 SRW Cummins had. The only thing that was lower was my GVWR. The 3500 SRW was 10,100#, the 2500 was 10,000# even. The 2007 Cummins downshifted less, but I dare say a stop watch would see them nearly the same towing the same 12k 5er that I did with both. Real world facts.

The gasser got 7-9 mpg, usually 8ish, the 5.9L Cummins got about 9-11 mpg, usually 10ish hauling the same 37' 5er. Real world.

You do realize that in 2013 Ram finally woke up and put some real numbers to their trucks? Heck my DD is the proud owner of a very nice 2004 Ram CTD 3500 DRW GVWR 12,200#. If I were to buy a 2013+ Ram 3500 CTD SRW with a GVWR of 12,300#I am actually looking at a lightly used 2013+ Ram CTD DRW with a GVWR of 14,000#

Then there is my 2001 Ram 2500 CTD with 3.55's and a 5 speed manual, it has a small timing chip and RV275 injectors, can pull 55 mph up a 6% to 7% grade coming out of a 45 mph corner, in 4th gear (direct drive)pulling our 12,500# 5er, 20,500# GCVW.

I hate to get rid of this truck, except I am currently well over the 8,800# GVWR.
