Be happy with 16 mpg, as you won't get any better than that driving 70-75 mph or more with your RT. How many miles on your truck?? They get better mileage after 4-5k miles.
Best I can get on the highway = 16.5 mpg, not bad considering all the engine mods I have. Too bad city is in the 12.5 mpg range.
