Well maybe not but driving from texas to ok. I do good to average 16-16.5 mpg. I have to believe the 3.21 would help. If I can’t get better I may have to go to a Chevy diesel
I have a 21 Laramie with 3.92 gears and am interested in swapping with someone that has the 3.21. My fuel mileage is just horrible with the 3.92 and I don’t really care about the towing capacity. I am in north east texas if anyone is interested in a swap.
