i just traded in my 2015 RAM 1500 crewcab v6 with 30,000 miles for a 2018 bighorn hemi with a 392 gear v6 had a 321. The v6 averaged around 22 mph to work and back while the hemi is angering a little over 20. Not much difference at all especially when the 18 has a 10,250 lb towing capicity compared to 4400 lb for the v6. Just thought this info might be helpful to someone trying to decide between the v6 or v8. Also so far the v8 gets better mileage towing about 2mpg. Red is the 15 black is the 18.
