I have a 2018 GMC sierra 6 sp 3.43 rear 5.3 engine 2 wh drive. I cannot find the GCWR on this truck but I am contemplating a trailer with following specs -
GVWR 5692, Cargo cap 1580, UVW 4112, Hitch 412. The truck factory curb wt is 5300 lbs. I will have one passenger and one driver both around 200 lbs. ea and about 200 lbs in the bed. Will this truck handle this trailer?? Thanks and appreciate your assistance.

Yup, you'll be fine. I have a heavier truck with the same engine and gearing and a trailer near the same weight (3,600 loaded) and we had 5 in the truck and were a few pounds over the rear axle and under the GVWR and way, way under the GCWR.

I tow a 10k trailer with the same as 2016 chevy 5.3 6 speed 3.42 axle 4wd crew cab.
You sure won't have any issues with that size trailer.

Sounds like the 6 speed behind the 5.3 is a vast improvement over the 4 speed. I had a 2007 1500 Silverado with the 5.3, 4 speed and 3.42 gear and thought it was a gutless truck in the rolling hills of Missouri. Out trailer at the time was Jayco 26BH, around 5,600 lbs loaded.

If the truck does not already have it, the best thing you can do is add and auxiliary transmission cooler.

If he has a receiver hitch he has the aux cooler, in fact I don't believe you can get the 5.3 without it.

The GCWR is right in your owners manual. But as said previously, that truck will handle that trailer with no problem.

You do not need GCWR in reality, what you need is the CARGO weight available.. The trailer tongue weight becomes "cargo" of your tow vehicle.

That information is now on a mandatory YELLOW sticker which typically is placed on the drivers side door or door frame.

Looks like this..

Yellow sticker weight has already taken in account the driver and full tank of fuel.

You would subtract your passenger(s) and any other weight added to the cab or bed to get the max tongue weight you can have.

Rather than have internet keyboard jockeys guess your vehicles specs, it is bets to find your cargo weight and figure it out yourself.

My Tahoe (payload 1585) was and my Siverado (payload 1,712) is very near your specs and it pulls Winnie's 5,200 pounds fine.
