Looking at new Chevy 1500’s and 99 percent of them have the 5.3. Have been looking for a 6.2 but they are a unicorn. Anyway how does a 5.3 handle around 8k lbs? I don’t really want to order it.

I have a 2015 with the 5.3, and its a dog towing my camper (7700lbs). My next one will be the 6.2, even if I have to order it and wait. Its a fine motor when the truck is empty, but it is not good at all towing.

You can get 3.42 with the 10 speed transmissionDon’t most of these new Chevys come with stupidly high gears? Like 2.92 or something?

I would hate to pay the 6.2 fuel penalty all the time I drive
My 6.2 powered Denali actually got 2mpg better mileage than the 5.3 Tahoe it replaced. Granted, this was in the mountains of CO so I'm not sure that would translate everywhere but the 6.2 just didn't have to work nearly as hard as the 5.3 going up grades while sucking wind at elevation.
5.3 with the 4 speed vs 6.2 with 6 or 8 speed?
The newer 5.3s feel a lot stouter than the older ones. I don't know if they're hotter motors or if it's the 8 or 10 or however many speed gearbox they're using now or a combo of the two.
With that said, the 6.2 is still a BIG difference. The 5.3 is a damn good engine. The 6.2 is a beast though.
GM loves to force you into a luxury package to get the 6.2 though. To their credit they got me. That's the only reason I bought a Yukon Denali. If I could've gotten the 6.2 in a more modestly outfitted Tahoe I would have.
5.3 had a 4 speed and the 6.2 had a 6. Driving my parents' 5.3 with either an 8 or a 10, it's a big upgrade from the old 4 but it's still a far cry from a 6.2.
axle gearing doesn't mean shit when you have a 8 or 10 speed trans, drop it down and let it spin. and my 6.2 DI was a fluke, it got 20 plus mpg all the time. my 5.3 DI motor would not do that in a lighter truck.
well in any event the trans is the source of your mileage variance, not the motor.
Any 5.3 will intermittently tow 8000 lbs just fine, it just has to spin faster than it does empty. I've pulled an equipment trailer at 11k gtw with my '12 5.3 3.43 and it was fine, I just manually selected 4th as the max highway gear and the let motor spin. I'm sure the even newer 5.3's with more power and speeds would be even better. I would hate to pay the 6.2 fuel penalty all the time I drive just so I can accelerate a little faster towing. If I was towing half the time maybe it would be different but at that point why discuss a half ton.

Dont the gm 6.2 engines run on premium gas though? Nobody ever factors the extra cost of premium (or diesel) when they start mpg dick measuring.
Also the mountains do make a difference. You could tow 8k with a 4.3 here in FL easily.![]()
I think if I were to buy a new truck it’d be a Tundra. They put 4.30 gears or something close to it in some of their trucks. Probably pretty decent set up for towing, but I’m not sure how well a Tundra hauls.
No desire to buy any new truck, but GM hasn’t really wowed me with their crappy DOD-AFM system that’s hit or miss in when it might cause serious issues.
