Re: New Truck question(s)

Marv The HD engines will make more hp and tq at lower RPM by design. It's not all about peak numbers. They often have been engineered with more durability, better cooling, and longevity higher up on the priority list as engineering goals as well as they are used in HD applications.662Views0likes0CommentsRe: New Truck question(s)
I had a Ram 2500 with the 6.4L Hemi and 4.10s that I pulled a 37 foot 5th wheel with. It would not run in 6th (same as you) unless I had a heck of a tail wind. It would run in 5th or 4th however, with a decent RPM spread between the two. The reason I am telling you this is because running in 4th (higher RPM) or 5th (lower RPM) didn't make much difference on the "instant" mpg display. So shooting for running in the highest gear is really no goal to shoot for. Now, if the only way you can pull a load is with the engine screaming near redline constantly (not just during up grade pulls)_that's different. But I really don't think you're going to gain much making the swap you are considering. I'm no diesel fan boy, but it's simply a fact that they pull heavy loads much easier, and at lower RPM, and will get better mpg when comparing apples to apples. I lost about 20 to 25% going from the Cummins to the Hemi, but was still very satisfied. The 2500 series truck is much better suited to towing, but you won't notice a huge difference in power, though there will be an increase.665Views0likes0CommentsRe: Need advise from the Ram Owners
I had a 2014 2500 with the 6.4L Hemi and 4.10s. Had 2 Cummins trucks before the 2014 Hemi. I pulled a 12k 5er that was 37' long and had 3 slides. Never lacked for power with the Hemi. Got 7-9 mpg pulling and mid to high teens running empty hwy, depended a lot on wind. With the 8 speed, the 6.4L Hemi would be that much better than my 6 speed auto was. The diesel will pull better in every situation and get slightly better mpg while doing it. I was very happy with the Hemi, and for towing 11k intermittently, it would be my choice.221Views0likes0Comments
