Never heard of a truck getting better gas mileage from taller tires. I think the combination of bad aerodynamics and higher weight vs cars leaves you with very little headroom for taller "gearing".
My Cherokee has a 2" lift, a front skid plate that directs air down, and 31" tires (stock are 28"), and I only get 16mpg.
