Have 2022 1500 with a 3.0. The off the line performance was great. The mpg was unbelievable up to 45 mpg on some trips. Towed my 26’ micro light around the country for over 20,000 mi and averaged about 14 mpg. Right until it seized up at 39,000 mi. Really miss that mpg .
Hopefully you’ll enjoy the mpg too.
