RAM EcoDiesel a Flop for Towing

On a parallel note, I really don't think most of the posters here realize just how tough I70 eastbound up to the Eisenhower tunnel is. My 2012 in my signature crests the hill between 40 - 45 MPH towing my 12,000 pound fifth wheel. My buddies 2013 F350 6.7 tows his similar trailer at the same speeds. I don't remember the last time I saw a post claiming that the current generation HD diesel trucks are under powered, but by that measure it obviously is.

Yep, I'd agree with all of this. I wonder how many trucks can hold 55 mph towing near their max up that hill? I've always looked at tow ratings as having to do more with chassis capability and longevity, not a certification of how fast I can tow up ANY mountain out there.
