I put Duratracs on a 2004 2500HD and lost about 1.5mpg.
My buddy has a 2020 Trail Boss wit the 20" wheels and tires.  My 2020 with 18s and Duratracs gets about 1mpg less than his truck.  Both trucks have the 5.3.

I also have a 5.3.AT4....sorry I know you asked for 6.2....but just wanted to help. Mine came with the stock duratracs and I get about 15.3mpg mixed city/hwy.....I added a 1.5” leveling motofab lower spacer and the mpgs remained the same. I was expecting a difference but it did not affect them at all. Been running the level with the stock tires for about 10k miles now.

I have LT TB with 6.2L with the factory 18" wheels with Duratracs.  I am averaging 15mpg.  Best was 19.7 mpg.

I had Duratracs on my F150 before picking up my Sierra. The mileage was horrible, as was the  ride quality. I lost about 3-4 mpg with them and they womped like hell on the freeway. Had KO2s on my Jeep and loved them. Decided on Ridge Grapplers for the Sierra, getting them put on in a few days. Will see how they do. Best of luck!

That's about what I'm getting on my 20 LT TB w/ 6.2 with the 18" Duratrafcs. I have the gm cold air intake, borla atak catback, and the Stillen TruPower intake. When I was driving from East Tennessee to Southfield Michigan I got 19.8-19.9mpg with these mods, but that was before I modified the active areo shutters ( they block airflow with the Stillen intake). I haven't been on any long drives since, so it is hard to tell on hwy millage. Currently the truck is showing 16.4mpg and that is driving from Southfield to Detroit on the racetracks, I mean interstats/hwys .

I think lift and tires you will probably lose 3-4 MPG . The DURATRACS are indeed loud and aggressive but man they look good

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
