Calculated tow capability... Disappointed

I have a 2011 GMC Sierra 1500 with the tow package, HD cooling etc..

Max trailer weight is 9600 lbs

Meaningless...unless you own the stripper model (curb) with no
options other than the tow option and you weigh in at 150lbs

The generic formula is:

GCWR => TV + TT + cargo/payload/WD Hitch/etc

total GCWR is 15,000.

This is a good number and high for most REGULAR half tons

Proof of curb/stripper used to derive the MTWR

15,000 - 9,600 = 5,400 is the weight of the TV they used toi
derive that 9,600 MTWR

You are ok with the TV's weight, but will be in RGAWR issue once
the trailers tongue & cargo & WD Hitch weight are added

Trucks GVWR is 6800 lbs.

Half tons range from low 6K GVWRs up to 8K GVWR.

Yours is on the low side of regular half tons

Max Weight for Cargo and people on the tire sticker is 1507.

Front axle max is 3650, rear axle max is 3950

Example of next higher class TVs

+4K FGAWR
+6K RGAWR...about 2,000 lbs more than most regular half ton RGAWR
some even higher in the +7K RGAWR and some even higher yet

Since most all TV's will have their load/cargo/tongue/etc placed
behind the center point of wheel base...most of the added weight
goes onto the rear axle

It truly is NOT any ONE rating, but them all in concert down to
the limiting weak link in the food chain down to pavement....that
then goes back to ONE rating that becomes that weak link

You 'can' do it, but struggle and reduce the longevity of your TV

The ability to manhandle the setup if Mr Murphy crosses your path
will become an issue, IMHO
