I got a left-over 2019 Ram 3500 4X4 last June. It has the HO Cummins and 6-speed Aisin transmission, 3.73 rear end. Rated to tow over 23K and I think around 3,100 lb. payload. It gets around 18 mpg on summer diesel and will tow anything I will ever own. Paid right at $50K for a tradesman with some upgrades like bigger touchscreen, cloth seats, etc. It tows a 16K lb, equipment trailer like a kitten on a string. This is the best towing pickup I have ever owned, by far.

Here's a pic of it towing a dead F250 home.
