Spend some time out at elevation where the grades are steep and you might feel different. I would welcome more power than the 350/800 my truck has when pulling through the Rockies.

^^^I wonder how long the cooling system is going to keep the sweat of those 505 ponies when they have to pull hard up a long steep grade.

My measly 385/865 and the too few gears AISIN seems to be just fine towing West Coast at 35-36k combined.

^^^^I think if and when Ram gets back into the competition you'll have to trade that old billy goat in for some real horsepower.

Your grades on interstates are no steeper than here in Wa St at sealevel. No more than 6%, except short bursts to 8%.

Want to talk local, try 25% grades! Yes you have elevation to deal with. 3% loss per 1000' if you have a non forced induction motor. Figured that out in 91 with a TBI 454 at 14K gcwr, 500 below ratings in yellowstone. Going 15-20 mph up the 10-15% grades in the park. Went back a few days after 9-11 with a 6.5TD, Less HP, but at 16K lbs, puling the SAME trailer. But my four kids were now adult sized teens instead of 6 months to 6 years. Pulled ALL the hills 20 mph faster! 4000 lbs over gcwr!

Reality, i doubt ALL that hp is hitting the pavement in todays motors. THe Auto transmissions need more HP to motovate a 10 sp vs the lder 3 spds. The NV4500 behind my 6.5TD only took 25-30hp vs 40+ for the 88 with the TH400. The original 5 sp Allison took 60-65HP to operate. Yes we are getting more HP to the ground. But also using more HP in drive train loss too.
i would have no issues pulling an RV thru the rockies with my 05 dmax that was a 320/620 in reality. My 185/385 6.5 was a lot better trip than my 235/385 TBI 454.

Next February I will be out of warranty. If I want more power it will be easy to obtain.

I have driven the grades Marty is talking about in a VW Diesel 5 speed. Nice it had an emergency brake handle between the seats. So steep you would think you were going to roll backwards stopping on those grades.
