2015 Silverado 1500 with 6.2L Corvette engine
Anyone's thoughts on suitability for towing 2015 FC 28 rear bed?

My boss has a Silverado with the 6.2 supposedly 425 hp.
My Tundra 5.7 with 381 hp and 400 lb. ft. of torque pulls harder/stronger and has a bigger back seat.
But to answer your question- yes, it would work fine.

The reason the Tundra feels like it pulls harder is the gearing. Tundra 4.3 vs GM 3.73 or 3.42:1.
At speed on the highway, it's a wash. However, I find it interesting that GM won't put the 6.2L engine in a 3/4 ton, and they say it is because it is an aluminum block engine, and therefor not heavy duty enough.
So then, based on that, how will the 6.2L do in a 1/2 ton as a tow vehicle?

I don't know anything about a Corvette engine but when it comes to towing "low end torque" is the name of the game.
Back in the day it made a difference between a car engine and truck engine. A sports car engine would be tuned for higher rpm and less low end torque where-as a truck was typically tuned for low end torque.
There changes were made with different types of intake manifolds and different profile camshafts. Sometimes the cylinder heads would be ported differently.
I would compare the specs on the corvette engine vs a comparable truck engine.

Aluminum blocks are not HD enough for the gut wrenching, off road twisting and digging of pulling a backhoe through a construction site, for example. It's a torque thing when everything is in a bind, as is common for contractors, etc. while at GCWR. They are fine for towing heavy loads like an AS would ever see...or any boat, rv, etc. Please don't take it out of context as a weakness. In those applications where trucks are worked to the max, a four bolt main cast iron block is the only way to go. 2500s and 3500 are primarily built to that market. Max tow 1500 are primarily designed for the concrete cowboy weekend warrior.
Two completely different applications and markets.

I think hooking up that Airstream will make for one very happy truck!
All 420 horses and 460 footpounds of it.
Awesome rig.

Don't forget that the new ones come with the 8 speed transmission so 1st gear is lower than previously. Should make starting from a stop easier. Also, having the extra gears will, hopefully, reduce gear hunting.
Also, the L86 engine found in the Silverado is not identical to the LT1 Corvette engine. While I'm sure the two share components I'm also willing to bet that they're both tuned for their specific applications.
To answer your specific question, yes, I would think this engine plus the 8 speed and 3.73 gearing would make a great tow vehicle for a 28 FC.
More info.

Not to nitpick, but unless your boss has tweaked his, then he has 402 HP and unfortunately GM dropped the 4.10 rear gear for 3.73. Toyota however continued with a 4.30 rear which as we all know really helps.
The new 6.2will only have a 3.42, but will have an 8 speed trans which will effectively put the overall gearing back to where it should be.
In other words, no problem towing.

I wasn't sure of the Chevy's actual numbers. I was spouting a ballpark figure.

BINGO! We have an intelligent winner! While they share some block casting roots, they are far from the same engine.

Haha, I don't know about that but I have done an unhealthy amount of reading on the subject as I wait for my Yukon to be delivered. Also, I was wrong about the gearing, the max tow comes with 3.42s. If you're curious, my Yukon has been built and is at 4000 status.

I had a 2010 Silverado 1500 crew cab with the 6.2L/heavy towing package. At that time I pulled a 1999 30' Excella. It pulled the trailer well, plenty of power. It went up and down through the Appalachian mountains with out problems. As with all 1/2 ton trucks, the main issue with towing is that the low payload prohibits carrying much of anything in the bed when the trailer is connected.

The 2010 6.2 in the Max Tow came with a 7200 lb gvwr while the 2015 will available with a 7600 lb and the truck is basically the same weight so that should help the payload.

Some, but not quite enough, IMO.

I want a 2500lb (ish) payload capacity in a 1500 MaxTow.

That would be perfect, wouldn't it. I think I'll stick with the better ride as it's my daily driver too. My 08 6L with Max Tow works great for me but the new 6.2 I have on order will be a great tow and daily ride.

The 2014 Silverado I have now is the strongest for (5.3L) engine size, best fuel economy, best riding, best towing, quietest of any truck I have ever owned. If the 2015 with the Max Tow packages keeps all of the qualities and adds ~300 lbs of payload capacity, it will be an awesome truck!!!

What he said-
The 5.3 is the best combination of power and efficiency in the GM lineup. My favorite work truck ever was a 2003 Chevy with the 5.3. It is still in the fleet and now has 521,000 miles. Why did GM stop making it available in the Express van? The engine options now are the 4.8 and the 6.0. The 4.8, although a good engine, does not have the power of the 5.3 and the fuel,economy is no better. The 6.0 is a little overkill and the fuel mileage is bad, but not much different than the 4.8.
The 4.3, 5.0, and 5.7 were good motors, but nothing in comparison to the 5.3. We also still have a GMC pickup with the 5.3 and over 400,000 miles and no motor/transmission work has ever been done to it.
