I have the same set up as you , and any highway driving over 1800-2000 rpm and I can pretty much watch the fuel gauge drop.

Injectors should not be wore out to the point of having to be changed at115,000 miles.
What kind of mileage are you getting.
How good does it roll. I have run across several rigs with calipers that doesn't completely release and that kills mileage.
Have you ever packed the wheel bearings.

Mileage is around 11. I have been noticing that the brake light keeps coming off and on. And my front drivers side one squeeks when im driving a lot of the time.

Winter fuel, warm up time, hubs locked in, 4x4, not really getting up to temp are all playing a part.

Add up enough little parts, you can have something rather big.

I would pull those front tires and make sure the brakes are releasing... while your at it check the wheel bearings.

Okay so I think my thermostat is the problem. Coolant temp gets to the n on normal but that is it. And that was after driving 65 mph for 30 miles and 5 or so after that. So do I buy a new one of these? Or is there a way I can unjam mine and get it working again?
