My 2017 Ram 5.7 quad cab all stock I averaged 19.5 to 21.0 when I had 20K on her. I now have a 2019 Classic Warlock quad cab all stock and same tires and tire pressure as the last Ram. I am now averaging 15.7 to 17.0 for the same 2 hour trips I make every weekend. The only difference is the truck only has 1200 miles on it and I installed in channel vent visors. I expected a lower average during break in period but not 3 miles less per gallon. These trucks are almost identical except for the vent visors. I am not driving at high elevations either. Thoughts and experiences?
