Same for the gasser. I am entering my yearly itch for a new truck and thinking a F250 or 2500 gasser.

I had the 6.6 gasser in 2021 2500 Chevy. Loved the truck and engine. I wouldn’t get another diesel unless it was making me money. The 6.6 gas pulled a 22 ft flat bed with 79 hp Kubota with bushhog and disk no problem. Also pulled a 34 ft bumper camper. I got 18-19 mpg on interstate. I put 60k miles on it before trading it in to downsize. The ride in the Chevy is much better than my 2017 F250 if comfort matters.

Bought a 2026 2500 gmc sierra SLT with the 6.6 Duramax in June. Had a 2018 sierra SLT 1500 with the 5.3 and 94k miles and loved it but couldn’t tow the tractor safely. So far I’m very happy with it. The ram def rides nicer but I’m hoping after I level it with new control arms and fox shocks that’ll improve a bit. Either way I bought it to tow. Not for a Cadillac type ride. However, it Tows the tractor and all the implements with ease. I saw GM has a 8.3 mongoose engine for 2027. Power Numbers are impressive but I’m always nervous to buy an engine first year out.

If I go halfton I am going F150 crewcab, 6.5 bed with 5.0.
I don't tow super often so really don't need a 3/4 ton. But do have a 60hp tractor it would need to pull sometime swith a disk/bushhog and hope to get a larger 22/24ft center console down the road.
The big thing is you can get the F250/2500 for the same price as the F150.

32k on my 24 250 CCSB 7.3 I get mixed driving of 14-14.6, long trips 16-16.5 Will be hauling our 34' Toy hauler to Mena Ark in about a month, I've towed it maybe 50 miles to our place but this will be the first trip where i can give mileage and tow opinions. Previous towing was 06 2500 with the 6.7. Unloaded it's fun to drive and love the ergonomics. Love not having to pay 5.80 for diesel right now too.

There is almost no reason for anyone to do so. The difference in fuel mileage is made up for in fuel costs and everything about a diesel pickup is more expensive. A modern half ton truck with a gas engine will do about 99% of anything 99% of buyers buy one for. I have a 2024 GMC 3500HD gas and it is the last pickup I ever buy but it is overkill for what I use if for now and I ONLY use it to tow with, I almost never drive it without a trailer behind it and 90% of the time a 1/2 ton truck would do what I ask of my truck now. I run a sawmill as a side hustle so I use a truck to do a lot but most of it could be done with a 1/2 ton truck and what couldn't be done could be done in 2 trips.

No underhood transmission dipstick, no transmission drain plug, no rear differential drain plug, has known transmission issues, and lubrication flaw in the valvetrain that can damage both engine and turbocharger.
You would be wise to have an independent mechanic shop to go over it with a fine tooth comb. Borescope the pistons, check for metal in transmission pan, oil pan, and oil filter.

I think that's a generalization. Longevity comes into play for an HD truck that is doing real work. If you're towing heavy I would absolutely trust the diesel over the gasser (10k lbs or more). If you tow a few times a year, and then take the kids to ball practice, get the gas. There's also personal preference.
Fuel costs sucks right now but I get better mpg in my 2500 AT4 with 35s on it than I did in my half ton ram with the 5.7.
It's also an entirely different conversation if you get rid of emissions equipment.
ETA: I have a 2020 with 120k miles on it, 6.6 Duramax. The only thing I've had to fix was a downstream nox sensor. 120 bucks and 20 minutes of my time.

I know several cowboys who use gas HD trucks and get exceptional longevity out of them. I think the highest one right now is at 450k miles on a 6.2 ford that lives its life with 20k+ behind it.
Diesels cost wayyyyy too much up front and wayyyy too much to operate to make any sense for the extreme majority of private ownership trucks.

You've proven time and time again your opinions on vehicles are not based on factual information.
Your 6.2 Ford is about 5k over towing capacity at 20k.
You bought a shitty ram 2500 with coil over suspension and complain about payload and have turned it into some witch hunt against diesels. Get over it dude.

And blowing that whole "diesels last longer" thing to complete shite while doing it.

Rich coming from a guy with a sample size of one with 120k miles of occasional towing.

Assuming this is at like 65mph? I have big doubts this was going 80mph. Which is fine. I think the biggest issue with guys pulling something once a week or a handful of times a year is speed. Slow down. Everyone says it’s not about pulling it’s about stopping, and it’s a hell of a lot easier to stop if you are going 5mph under the speed limit then going 5 over.
ETA: the other thing about going slow, is it’s much easier to pass. Nothing worst than someone going the speed limit somewhere like a 55 zone everyone goes 65 or 70. If you go 50 then it’s super easy for people to pass you usually.

It saves A LOT of fuel. A rediculous amount, gas or diesel it doesnt matter. It takes a lot more energy to overcome drag at 80mph than it does at 60.
Where a diesel shines is ripping 20k lbs up a 6% grade at 10k feet of elevation at 70 miles per hour. If you cant stand to be passed up while towing your 5th wheel up a grade, you need a diesel. If you are frugal and only care about reliability and getting where you need to go, gas will probably serve you just fine.
The people who tout off "my diesel gets 20mpg whether its pulling anything or not" are full of shite.
But to OPs point, the current 6.6 duramax is probably the best engine out of the big 3. The denso fuel system seems to be very reliable. The rest of the engine and driveline seem to be perfectly adequate. I dont know a lot of people with them but the people i do know with them have only had minor issues.

Camping buddy has the 6.6 gasser, I have the 6.6 Duramax, both 2500
I get 17ish around town. 21ish interstate driving unloaded, 9-9.5 towing 43' 13k lb fifth wheel
His gasser gets 12-13 around town, 17ish interstate unloaded, 6ish towing his 29' box 35' overall length bumper pull, it's around 6k lbs

The 3/4 tons have to be more expensive to manufacture. That goes to show they are porking everyone who buys a half ton without any lubrication.

I was convinced the F250 7.3 was way to go and pulled trigger. Love it. Try to get a 2026 because they’ve reduced torque and HP in the 2027 F-250 7.3. Unless you pull heavy (15k+) all the time or have a Freeman 37, the gasser is the way to go.

Damn, they lowered the specs for the 27? What bs is that.

There is a lot of things we can give downshift shite about. Predominantly being a neck beard St.James baby deer killing SOB... joking!
But the man knows his diesel motors.
