I can't give you firsthand experience with the setup, but if you'll be more specific with the numbers that seem to say you're OK I can certainly validate your research with an (informed) opinion.

At a minimum I'll need GVWR (truck and trailer) and the payload capacity (from truck sticker). Any other detail will help (axle ratings, tire ratings, hitch rating, etc).

Howard

Your limitation is likely to be truck payload. What is the number on the yellow tire label on the driver’s door frame? Cargo weight must not exceed ??? Lbs. Your trailer has a GVWR of about 10,000 lbs. You should plan for a hitch weight approaching 15% of this (1500 lbs). The truck payload should cover hitch weight plus people and anything else in the truck. If all these numbers line up, your plan should be doable.

Rob and Howard are right on with those numbers. From a qualitative standpoint what wheelbase do you have on the truck? A trailer that long would definitely benefit from the longer wheelbase options (not sure on what GM's options are I am more familiar with Ford). My in laws towed a similar length trailer with a F150 with the 5.5" bed, 144" wheelbase. They found that even with sway control and being within the weight specs it handled poorly in the wind at highway speeds. At the other end of the spectrum I occasionally would tow his trailer with my F350 long bed, and did not use any sway control or weight distribution (different size receiver in my truck) and it towed just fine. That is just an example so show the difference that the weight and wheelbase of the tow vehicle can make.

3210BH:
GVWR: 10,195
UVW: 8,394
Tongue weight at max GVRW: about 1,200

2021 Chevy Crew cab 4x4 6.2L (making assumptions here):
GVWR:: 6,800-7,300
GCVWR: 15,000
Max conventional towing: 9,200
Payload: max 1,870
​
With max trailering package
GVWR::6,800-7,300
GCVWR: 17,800
Max Conventional towing:11,900
Payload:​ max 2,090

Let's assume you have the max trailering package with max GVWR. You take the GCVWR (17,800) and subtract your GVWR (7,300) to get 10,500 pounds left for the trailer. So with this package, the GCVWR is good. The trailer is also within the max conventional towing capacities. You will have to know your specific payload and tongue weight of the trailer to determine your payload capacity is good.

If you do not have the max trailering package, you will be over your GVWR capacity by over 2,000#. You will also be over your max conventional towing capacity by almost 1,000# and will likely be over your payload as well.

The truck will certainly pull the trailer without issue. It's the comfort level of the driver that determines how much tow vehicle you want.
