Stu, that sure isn't right . . . I would suspect you have an issue going on, even though you don't have the "Check Engine Light" illuminated . . . I have 2013 Ram 1500 4x4, 5.7hemi, crew cab, and have gotten 15-18mpg around town, and up to 23mpg on the highway (those would be USA Gallon figures, not Imperial) . . .

All city driving, my 2005 would get 10-11 mpg. If you idle a bunch it's going to be worse as well.

My 2010 hemi quad cab does about exactly the same, I’m happy with it. I think it’s reasonable for a 390 horsepower truck. I have a sprint booster on mine to get rid of the throttle delay, and real dual exhaust with two mufflers is all I’ve done to it.

those 10 and 13 trucks get much better than the earlier ones, 13-15 in town is normal and 17-19 on highway with the earlier ones, the later ones with VVT MDS get another 2-3 MPG.

The hills will certainly also degrade your fuel economy, not surprised it's a little worse than my truck was. New they were only rated at 12 mpg city, and that's assuming ethanol free fuel and no hills either. https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=21160

My 04 hemi quad cab short bed gets 13mpg... in comparison, driving to the same places, same way etc, my cummins gets 18. Where I live it's lots of hills and I rarely drive on the highway.

I have noticed i am getting lower and lower fuel mileage out a gallon of 91 octane (as required for this year engine) gas now it's right around 7 MPG and that's about it.
You should be getting double that mileage and you mention you've noticed it getting worse. I would do some investigating like making sure a brake isn't hanging up or do a plug reading to see if it's overly rich for some reason. Either could be a reason for no CLE.

What kind of tires are you running? I take a big hit mpg wise with my 05 QCSB 4wd Hemi when I put on my Duratracs for the winter (vs Wrangler RSA's for the summer). But yeah, 7 mpg is bad, I do better than that here in the dead of winter (-10 F here today) with my Duratracs on. Whens the last time you changed the plugs?

What brand, size and psi in the tires? High rolling resistence tires can reduce MPG by as much as 3.
On the highway 3.91 diff gears on an unloaded Ram pickup decrease MPG by 2 at a steady 60 mph compared to 3.21.
Camper tops generally increase air drag but it varies a lot by topper shape.
You can zero in on whether the tires and/or camper top is hurting MPG by coasting down a steep but steady grade hill in neutral.
They are 275 x 60 x 20 Goodyear Wranglers. I will double check the tire pressure later but they dont seem to be low. I did see going back though the original owner's stack of paperwork the truck was having problems right before i brought it with check engine light issues. The shop the owner took it too did change the plugs at about 80,000 miles. That seemed to fix the problem. You can see in 10 years i have not put on many miles at all.

Man Stu, it looks like you really do drive quite locally. I hope the thing gets up to temperature for closed loop and all that, or it will remain a pig. Them San fran hills do not help. I live in Chi suburbs, and my 4.7 durango is at 16 for long term average mpg. Once i can get on the freeway and stay at a steady flat pace i can get near 18 MPG at 65MPH.
