Same here. After seeing the interior of the RAM, Everytime I went back to look at the Chevy, I couldn't "un-see" the RAM interior lol

31364 miles on it. I've driven it for 1200 of those miles. I reset the trip a and to b when I bought it

If the previous owner towed a lot, it's likely due for a rear differential fluid change and an oil change

I really liked the GMC AT4, 5.3 with 10sp was nice and I am sure good mpg, but the interior space......

My previous truck was a 2016 GMC with 5.3 and the 8sp(the single worst transmission to ever exist and I have owned the Chrysler ultradrive....) and the MPG was about 16-17 city and 24-26 highway.

yeah my 8 speed in my gmc would clunk on down shifts alot but it never broke lol

Since I’m in the camp of lousy MPG, I just tell myself my Hemi makes more HP than most other Hemi’s. Mine’s a high performance engine. Bonus.

 

[SacRebel]

After 18k miles I’m getting 13.3 mpg, no towing or hauling.

 

[FiremanHemi]

Horrible gas mileage since day 1 for me LOL and even worse after the 35’s but I haven’t recalibrated the speedo yet

My 2020 Laramie with 33” LT E rated tires gets 18-19 on the hwy easily. Towed a 4800 lb camper through the mountains round trip for 200 miles this past weekend and averaged 11 mpg. I don’t understand how some of you can get such bad fuel mileage. The only thing I can think of is those stuck in stop and go city traffic, I don’t do very much of that.

Stop and go traffic...and racing to be the first at the next light.

I have a little over 10k on my 2020 Bighorn and in the city I'll get right around 15 mpg but on the highway the most I've gotten is about 17.2 or so..not even close to advertised 23 mpg. I don't run the mds but that saved about .5 mpg when I did.

 

[BowDown]

I have 16K and average high 17's to 18 mpg, hand calc is 420 miles / 23 gallons = 18.2 miles per gallon.
You guys getting bad mileage, how are you driving the truck? I'm not not the 1st through an intersection but I'm not the last and I try to keep the truck shifting by 2000rpm, no higher than 2500 rpm when accelerating.
This is 70-80% city driving and rush hour traffic

 

[redneck]

yeah i try to keep my shifts at 4k some times over these things have no low end tq.

 

[Caulk Boss]

Well towed my 6x10 enclosed trailer today to job site and back.. 75 miles round trip.. never went over 72mph...................

10.3 mpg

 

[Neurobit]

13.3 seems very, very low for hwy no matter which wheels or rear end you have.

I have a 3.21 w/ 22”s and I get ~18MPG if I drive 75-80MPH.
If I keep it at 70MPH, I’lll get 19-19.5.

Have had this 19 Longhorn for 8 days.. 1168 miles . 750 of that was driving home from dealership.. no towing.. and I average 13.3 miles per gallon.. driving on highway averaging 70 to 75 mph.. and then some in town driving.. stock 22 wheels and tires . No mods .

Is this what I'm about to expect?! WTH

Knock 10 mph off and you'll likely see some improvement. 75 mph with your combo isn't going to produce anything close to the sticker. Which is based on the lightest/least optioned package with tallest gearing, usually at 55 mph. Look at the bright side; at least you have the 33 gal tank lol

I accelerate at about half throttle, and have the trans shift between 3 and 4K rpm. Once at speed, I set the cruise and let mds do its thing if possible. Also, the mpg is pretty lousy until the engine gets to operating temperature.

What combo? His truck is stock. It’s understood that the faster you go the more you burn, but he should not bee seeing extended Hwy ~13MPG regardless.

If he were to drive 55MPH, he should be seeing >20MPG. Prob close to mid 20s.

Heck, I don't even think I've gone over 3K RPM since I've owned it.

It will go up to about 15. Idling the engine kills the average the most.
