Gas Mileage???

Wow! I was getting 18.0 around town and 22 on the highway with my 2022 Laramie and the 5.7 Hemi non E-Torque. I wish I would have kept it now.

21-25usmpg, but that’s and Ecosdiesel. 16-19 towing 7609lb 33’ trailer

The Hurricane and Hemi are close to the same mpg.
However, the issue is really your Rebel trim. If you un-Rebel it, mainly the 33" Duratracs, and replace them with similar tires (i.e. smaller street oriented) as your previous RAM you should get pretty close.
You still have a 1" lift, but the mpg from that is marginal. I hate that RAM doesn't adjust the Rebels mpg down to compensate for the tires like Chevy does on the Trail Boss. They are allowed to blanket state the EPA rating to all similar configured trims (i.e. crew cab 4x4s), but the EPA does allow them to adjust down any trim if they choose, but Stellantis don't which is fraudulent to me.

Well. There's your problem.
You're pushing a vehicle with the aerodynamics of a brick to 75mph.
As a test, try slowing down a bit so the engine isn't working so hard to push the air out of the way.

that's because the rebel has 3.92 gears and your Laramie more than likely had 321 or 355 which is allot better on highway gas mileage.
I did a trip from North Dakota back to Indiana. This trip made me realize these trucks dont get great gas mileage going 70mph and above. Add in headwind and its worst. The sweet spot seems to be 50-60 and i can get 19.
Ur truck only has 500 miles on it so its not broken in yet. IF you think its mechanical. Sell it and buy a car

I got a 2025 rebel with 4000 miles and I'm getting anywhere from 15 to 17 on city and 16 to 19 on highway depending on the wind and how fast I drive of course. if I drive 75 to 80 I get around 15. if I stay under 65 I get 16 to 18. I'm also using 93 gas sometimes 89, it says you can use 87 but if you read the manual the manufacturer recommends 93 for optimal performance!

Sounds like its working as designed, just like mine. It's got the aerodynamics of a dumpster, has a one-inch lift, 33 inch tires, and is four wheel drive.
Keep in mind too that at 75 MPH you are travelling roughly 36% faster than the 48 MPH average speed used in the EPA "Highway" fuel economy test.
Your truck is getting the mileage it was enginneered to get; it only APPEARS to be broken bc you were kind of bullsh!tted by the dealer/window-sticker, and you were travelling way faster than the speed used to generate the "Highway" fuel economy figures.
My wifes Honda gets over 40 MPH at Interstate speeds, but she can't haul cool stuff like my truck can, so I guess its all tradeoffs.
Here's some reading from Car and Driver on the history of the fuel economy tests: https://www.caranddriver.com/features/a15388892/the-truth-about-epa-city-highway-mpg-estimates/
I will give my truck credit for this though, if I run non-ethanol and I'm cruising at 55 MPH with no stops on State highways, I can get 19 MPG. Ethanol, faster speeds, and getting back up to speed from a stop all serve to reduce fuel economy; add in a little stomp-and-go with the 5.7 and it makes things a bit worse.
Also, there was no improvement in mileage after some type of "break in" period for my truck, its got 30,000 miles on it now, and its performed the same since Day 1.

You'll probably find the sweet spot for MPG around 60+/-. Try that.
I was getting the same mileage with my 2025 Rebel. I purchased it in June. Put just over 10,000 miles on it. But on top of the crappy fuel mileage. Mine was in the shop 4 different times for electrical issues and body panel rattles. Finally made the decision last night to just get rid of it. Traded it for a 2023 Ram 2500 Cummins. I purchased my first new ram 1500 in 2000 and I have purchased 10 since then. The rebel was best looking of all the ones I've owned. But it was also the most expensive and the biggest piece of crap of all of them. Now that ram did away with the V8, I am done with 1500's.

So what was the purpose to get rid of the 5.7 of the Hurricane gets the same mpg? Why did they not fine tune the 5,7 a little more and just keep the greatest V8 MOPAR ever built, you have to wonder?

I still do not understand why they stopped the 5,7 that got just as good MPG as the 6 Banger?

Emissions and improved performance. The Hurricane produces less than half the CO2 the Hemi does while producing more power overall.
There really isn't a way to tune the current Hemi to make it emissions compliant for the future. They need a clean sheet redesign, which is what GM is doing for their small blocks, but you need a CEO who understands the importance of their V8 engines and the budget to do it. Tavares didn't have that vision or interest to do that.
However that could be changing. Besides the strong rumor they are bringing back the old 5.7L for US production and including it on more basic trims of 1500 trucks, they could be considering a new generation of future V8.

That would be such a good move to keep the 5.7 and offer the new Hurricane. I personally like the 5.7 but not opposed to the Hurricane. Also, it may be the CO2 requirement will be dropped as well since we have a POTUS who is ready to stand with other countries who are building new Power Plants that we have discontinued while laughing at us with old out dated grids as well.

2wd stock size tires non ET hemi, if i take ie easy 18-19 around town 24 highway at 65-70 any faster or i mash out it kills my mpg's according to my dash and i'm not going to do my own calculations to check that. idling also kills it so i dont idle it for long to warm it up on cold days. plus it actually warms up faster if ya drive it. i didn't buy a full-size truck with a almost 400 hp engine because i care about gas mileage. but i get it you want to still get the most ya can out of a gallon. i'm waiting for the drilling to lower the cost of fuel. TRUMP don't let us down man.....

I'll Drink to that!!
If I stay out of it on my Rebal I can get 13mpg in the city and 15mpg on the highway. But I also didn't buy it for good mpg.
