...well you might be mindful of needless accelerations....so the guy behind you gets a little testy...big deal...you don't have to impress anyone with your rapid acceleration...if not haulin' take the economy car instead~

The obvious is a ring & pinion / smaller rear end gear ratio but acceleration will suffer but top end & mpg will improve. Example like a 4:10 ratio changed to a 3:23, bigger dia. tires pumped up hard ,for less rolling resistance, smaller mm fuel injectors? a flush hard bed cover for better air flow, that bed catches too much air & drag, & look into finding & buying a "Hone-O-Drive" unit that mounts to the rear housing, people have been successful with these on RV's & Hummer's (if you can find one) it adds an overdrive gear up to your final drive.

best way to get better fuel milage put a cold air intake on and a good cat back system it does help and gives you some more power

get a diablo trinity along with intake and exhaust it gives you better mileage I have one being hard on the gas i get 13.9 mpg

I have a 2013 RAM 1500 Quad-Cab 4x4. I average around town about 16-17 MPG. On long haul trips with cruise on I get about 17-17.5 MPG, without cruise on I Avg. about 18.5-19 MPG. The newer 2015-2016 1500's offer better MPG, but you lose some of the horsepower of the "HEMI." Sure wish they'd have not cut corners with the "HEMI" edition. I wouldn't mind the MPG if it were a true HEMI (426 cu. in.).
