Has anyone had problems with the gas mileage? This truck sticker epa rating was 19 city/24 hwy. I know its hard to get what epa says because they don’t run A/C, flat terrian and such. But every Ram truck I have ever bought has been within a couple mpg. This truck, yes city, Im getting 17-18 mpg but highway at 75 mph is only getting 15 mpg, its crazy. My old Hemi got 18 hwy
