The 6.2 doesn't have a significant towing advantage over the 5.3, and it's heavier so you have a lower tongue weight. Either way, if you're looking to push numbers at the top end, you're likely going to need a 2500. I wouldn't tow anything over 10K# with a 1500 on the regular.

The 6.2 is a beats of a motor, but the 1500 is maxed out in other areas at those extreme weights.


Edit to say. The 6.2 also requires premium fuel, or it runs all retarded.

The additional torque of the 6.2 makes the motor not need to "work as hard" as the 5.3 does in most scenarios. Yes, it requires premium fuel, but when you look at the total cost of ownership of the truck combined with the overall capabilities, it's one of those "upgrades" that likely ends up worth it in the long run because it enhances just about every driveability aspect of the truck.

Is a 2500 a better tow vehicle? Yes. Is it worth buying a 2500 versus a 1500? For the general consumer, almost always no. The additional expense of the larger truck is far more than what you would spend in extra gas or even paying to have those large loads transported for you based on the very low amount of miles most people tow for compared to when they don't tow.

I've been looking to replace my truck with a new one and won't even bother going to the dealerships because no one is stocking the 6.2L motor-based trucks around here and I'm not interested in placing an order and waiting.

Had a buddy looking at 2500 GM 6.6 gas. He built a 1500 and a 2500 Silverado online and interesting enough the 2500 gas truck with what he wanted was cheaper than the 1500 he was looking at. He built an LT which I believe is the middle trim for the HDs.

I've got 12000 miles on mine and never had any excessive or any additional oil loss, had no issues with mine whatsoever. Love it.

For towing I would go 2500HD custom with a 6.6 L8T. You can get them new for around 50k.

The primary issue with rockers/lifters on these small block engines is the AFM causing failures. You can buy an AFM disabler that plugs right into the OBD that solves the problem.

Added bonus the 2500 6.6L gas from what I read doesn't have DFM like the 1500s do.

I thought I had seen where the 5.3L had AFM/DFM and the larger gas engines had "Stop/Start". No?

HD Gas engines like the 6.6 don't need to meet certain standards that 1500 trucks do. Which is why the Fuel economy ratings on 2500 trucks say NA for city and hwy mpgs on the window sticker. So they do not have DFM or start stop which in turn makes them more reliable.

There are literally millions on the roads between GMC, Chevy and Cadillac. It's a really small percentage of the total engines on the road. Just like the 3.5l Ecoboost intercooler uproar. Yep, some had issues but very few in the total production but because of the noisy victims, you'd of thought it was a certainty. A vast majority, like me, never had any problems.
I just bought the 6.2l and not losing a second of sleep "worrying".

If you don't mind the cost of diesel, go for the duramax.

This is how I present the comparison for folks shopping the 5.3L vs the 3.0L. If you're buying a duramax thinking that you'll save money, remember that diesel is almost $2 more per gallon than regular unleaded. You might not be saving any money at all. You'll get better highway fuel economy and you'll have more torque for towing but the added cost of fuel might be a wash or end up costing more in the long run.

If you're shopping the 6.2L vs the 3.0L, get the 3.0L because premium unleaded is closer to diesel in cost per gallon and the fuel economy difference will make the 3.0L come out ahead in the long run.

If the 3.0L was available in the ZR2, I would have bought it over the 6.2L. I will also add that the 3.0L is overall more reliable than either of the V8s.

That said, I think the best overall powertrain that GM has right now in terms power, fuel economy and reliability is the 2.7L HO.

I have the 22 Refreshed RST Rally Sport Edition. 5.3L. Wanted something a bit sporty with out that lowered lookl.

Zero Problems towing a 22Ft boat.

Only mods are ditching the stock tires (22's on the RS) and grabbed some hybrid ridge grapplers and leveled the front end.

Highly disappointed in the leather quality and would love to choke out the engineer who decided to put the spedo on the left side. What an idiot. Hopefully a future software update allows you to flip it.

As for gas mileage im lucky to get 16 around town and 20 on the highway. I've been getting more like 13 / 17 but nothing beats the storage and capability of a truck for daily life.

The V8 issues are real and they are definitely worse than ever before. There are over 2k 6.2L engines on backorder right now for GM service departments across the country. These are all warranty replacement engines too. That doesn't include the replacements that are customer pay. The wait time for a new engine is at 6-12 months.

Can you imagine buying a $75k ZR2 or Denali and having the engine blow up at less than 8k miles and then having to wait up to a year for a replacement? It sucks and it's a reality for a lot of owners right now. The first ZR2 we sold 8 months ago is sitting out back with a blown engine at 7k miles right now. No idea when GM can get a replacement either.

I've seen enough of them here that it's definitely on my mind with my truck.
