My old truck also was around 2800 at 55 and got about 15 but around 3200 at 75ish it got 23.
Glad i read this. With the tires I have on my runner right now and the stock gearing I am turning about 2500 when i am doing 55 according to my GPS. I wanted to regear it to correct my speedometer but was worried that having the engine turning faster would hurt my milage even more than it is already. Best milage I have ever gotten while I have had the truck is 14.
Knowing this, if what i heard about the price on Differentials for the Christmas sale is right I am going to have to jump on it
