I have a 2017 1500 4WD that has a lift kit and 20" tires with the 3rd gen in it. It has 117548 miles on it and averages 22 mpg on the highway and 20 in the city.
When I hook my trailer and load the Polaris Ranger it drops to 14-16. Have never had an issue with it but there have been several recalls.
I really like the dang thing..................YMMV
