I bought this truck because I had an awesome 15 years with my last ram. If I can't get this thing fixed, it will unfortunately be my last!

I really wish you were calculating it wrong but I got the same results when I used your numbers. I'm going to throw out a bunch of questions to see if wee can figure this out. I get 15 around town with my 4.7 RCSB 4x4
What octane do you run? What air pressure is in your tires? Are your wheels well aligned? Have you tried gas from another station? Have you checked your air filter to see if mice made a nest in there? Are you in 4 wheel drive all the time? Have you tried another dealer?
I hope one of these questions will give you an idea. Your mileage is about half of what I get. There has to be something wrong.

I put the tires on as soon as I got the truck so I couldn't tell you if there was any difference there, however, is it possible the tires can make that huge amount of a difference? I can't really see that as I have 20" wheels which have considerably less sidewall than say a 17" wheel.

Hard to believe that there is a mode that the engine could run in which would get that kind of milage unloaded.

yeah, I'd say the 20s help with the sidewall flex. The tires are fairly aggressive but not crazy. You'd lose some MPGs for sure but I'm talking 2-3 mpg tops if they are anywhere close to stock size. At 7.5 mpgs there is clearly an issue or you have to have about the poorest driving habits imaginable...
Oh well, guess I best just suck it up because I can't afford another new truck. Looks like I will be snowmobiling to work lots this winter!!! lol

By any chance do you hit start and not notice it running in the driveway? LOL
I knew a blonde once that left her car running in the drive because the battery was low. It ran out of gas and sh didn't know why. She wasn't driving it so how could it use gas?
