I would look for a 2018 or newer RAM 6.4L Hemi. That is the the first year for the 8 speed auto trans. I have a 2017 6.4L, 6 speed with 4:10 axles and it get 1 mpg less than the Diesels. Diesel is great if you need it. I don't purchase for the 1% use.
Does anyone know what the RPM difference is between the gasoline and diesel engines when towing an equal load?
Yes , diesel 1800rpm.... gas 4500 rpm
Damn. 4500 RPMs for an extended period of time would get old.
Simple look at the torque curve , the Cummins peaks at 1800 rpm and most gas engines peak around 4500 rpm. I have hd trucks with both and this is true.
I will say me Chevy 6.0 at 4500 sounds pretty sweet
