Don't know about the 6.0 GM vs the 6.6L Dmax but my 345hp/365ftlbs '05 Hemi powered 2500HD Ram towed our previous 10,400 lb 5th wheel up the grades faster than our 250hp/460 ftlbs '03 2500HD Ram. With horsepower you can make torque through gear reduction. That extra 100 hp made a pretty big difference at highway speeds.

Here we go again Hannibal, comparing apples to oranges. I have told you before I believe, I will be more than happy to meet you somewhere with my stock '05 cummins and we can do some test runs. Your 345 hp/365 lbft against my 325 hp/610 lbft. I'll bring my 18,000# trailer and you can pick the 500 mile route.

I see you now have a 2010 5.4 Ford? 320 hp? even better comparison. You should have the 6 speed trans, better for you. I'm still up for the test, are you?

My 2010 5.4L F250 advertises 310hp/360ftlbs and has a 5spd TS transmission. What your truck has to do with my two previous trucks and how they compared towing the same 5th wheel, I don't know. I'm well beyond the age of racing up grades to prove a point. My comparison between my two trucks is fact. Just the same, if you're going to expect me to believe you tow 18000 lbs up a 6% grade 65mph in O/D, you need to cut back on the burritos. If we're ever in the same area and it's convenient, I'd be happy to hitch up your 18000 lb 5th wheel to my truck for no other reason than to see how it does good or bad. Fact is, if the grade requires 300hp to pull, your truck will be at 3k rpm, mine will be at 5k rpm IF they both produce their advertised HP. As elevation goes up, mine goes down. You'll never see a post where I've denied that. I can easily afford my 7th diesel pickup. If the gassers didn't perform to my satisfaction, I would be back in a diesel long before now.

I'm not talking about a race up a hill either. I was just stating that you were comparing "your" 2005 Hemi to your 2003 Cummins. Not Apples to Apples. If you were comparing your 2005 Hemi to a 2005 Cummins then I would say O.K. There is 75 HP and 150 lbft of torque difference between an 03 and 05 Cummins.

No I'm not saying I can tow it at 65 up a 6% in OD in stock form. I can do it @ 70 with stock tires but not at 65. 68 is when my truck kicks out of OD with my foot on the floor in stock form. With the size tire I have now it kicks down at 74. But like I said, I'm not racing, just holding my speed. I like to run between 68 and 72. That's where I get "MY" best MPG (programmed)with my 13' tall 5er which is 10-11 depending on head wind.
