Since you have decided on a gas 3/4 ton class truck, I would take a close look at the
2019 Ram 2500 with the big gas engine.
My last truck that I towed with was a 2016 Ram Laramie 2500 with the Cummins diesel engine (in signature). That truck was a complete pleasure to drive, both towing and empty.
Only reason I don't have it now is that we are not towing anymore and diesel engines don't play as well as gas engines in our cold Michigan winters. Besides, it was a great excuse to get into another new truck! (See my profile):W
