Towing with Dodge 6.4
Anyone have towing experience with towing with the Dodge with the 6.4 engine? I'd be towing an 8000 trailer,and was wondering how well they pull,up hills and such. Thank you

Your averaging 15.6 MPG's? I must have really gotten screwed or I am doing things horribly wrong, the best average MPG's I ever averaged on my 2012, 2500 with 3.73's was 12.5 hand calculated. That was with a fairly equal mix of city and highway driving.
With the new 6+ speed transmissions, the 4.10 gets better mileage than the 3.73 in many cases. Some with 4.10 have reported 1-2mpg higher with city driving and only slightly better highway than the 3.73... Wish I had ordered the 4.10 on my 2011 GMC 2500HD instead of the 3.73 that I have... with 3.73 gears I have averaged just over 15mpg on a couple of tanks with mostly highway (speeds under 60mph). Freeway tends to be a bit lower, just under 15mpg. City I get 12-13... Towing I get 7.5-8.5mpg at 58-62mph. I might be able to get towing mpg up to 9 if I turn off cruise before any grades or hills..
yes, all hand calculated.
Interesting......I always thought the reason for numerically lower gear ratios eg. 3.73 was to get better gas mileage at the expense of less pulling performance.
So with the 6.4, the 4.1 performs better AND gets better gas mileage?? If true, I need to strongly consider this platform!!
That is more dependent on your driving style and city vs highway percentages. A higher numerically rear gear is not a huge penalty with city driving and and can actually improve it. But highway you will burn more fuel as you will always be turning higher rpms at a steady speed and same transmission gear.
