Yep. And nobody needs a 2500 Ram to tow a 6,500 lb trailer.
My 1500 Eco Diesel has:
8 speeds,
No MDS (Mad Derangement System) on a diesel,
Manual Shift buttons on steering wheel,
Tow/Heavy duty button modifies shift points,
The highly convenient out of the way fun Spin O-Matic dial shifter on the dash,
3.92 gears,
tow capacity of 10,800 lbs
cargo capacity of 1600 lbs.
I can engage the cruise control in the mountains while towing a 6,500 lb trailer and kind of forget its back there.
While a gas engine revs higher (and is considerably noisier in the mountains) a properly equipped 5.7 Ram can tow and carry about as much, if properly equipped.
You don't need a 2500 Ram.
