The aero of this vehicle is probably pretty bad, sits up high, big tires, no flow. But do you spend time on the highway, or is it mostly stop-n-go rural box hopping? Is the 4WD really needed? that adds weight.
Is it performing similiar to the published MPG figures, or much worse?
Is another vehicle an option? Would be lots of choices depending on the above answers.
