This is my last 200 miles. 37” tires, 3” lift. Mostly back roads, 55-70 mph, and a little in town driving.

I find the calculator on mine to read high based on my actual calculations. I'd suffer checking against real math before quoting the machine. Never had a car that was accurate

I got right at 21.8 MPGs on a trip to Virgina to pickup Rubi rails for mine right after I put on the lift and tires. Best I have seen with the current setup is 19.3 MPGs. Normally average 18.7 MPGs total.

I guess you reset your counter while driving to get a 48mpg. No way in hell. Better make a call to service dept because your readings are way better then what FCA says you should get in fact better then 99% of most cars on the road.

I've never gotten as low as 17 or 16 unless I drive it like I drove when I was 16.............. these days, pushing it, higher speed drives, that sort of thing, I bottom out around 19.

I mentioned to my dealer last week that I had a complaint about my truck. He sort of looked concerned - then I said the fuel economy is all messed up - EPA said I should do only so much and I've been getting 23+ without much trouble.
He laughed and said "you know how many I've heard that from?, I'm not surprised"
Highway driving over 65 kills the MPG - over 70 really sinks it, over 80 don't even look at your MPG - change your screen as you can't be serious about anything pushing a tall brick that hard. That engine is struggling hard against wind resistance when doing more than about 65-70.
Expect mid-teens if going over 70 or sliding up to stops then full-throttling the take-off to reduce reaction time down to .000001 second.

Stock Glad Altitude was 24.4 at best.
Pulling the trailer with two wheelers was 16.5.
Had a change of tires and it's been different here lately. 20.5 maybe with general grabber apt 10 ply. Same stock 18 inch rims just a heavier tire in same stock size. The bridge stones were trash and nothing but problems. Really surprised about garbage tires on such a nice rig.

12.5 -14.5. Stock Mojave. I drive it too fast, and a speed up too fast. Not complaining. On a side note, I got about 17 mpg regularly with my wife’s quad cab,4WD,Hemi, Ram 1500. Drove it like I stole it.

I routinely get (calculated fill to fill) 19+ bopping around and 23+ on the highway (70-75 mph cruising). Drop one mpg for the winter. Stone stock Overland. I also get about 13 mpg towing my travel trailer (5,300 lb loaded for camping and 27' long).
