May be buying a 2004 Jayco Designer M-28 FBS, weight 7020 lbs, dry hitch 1075 lbs. I have a 2014 GMC Sierra, 4WD, 5.3 L, 3.42 ratio, crew, 6.6 box, trailering package, but not the max package. Book says max weight 9600, tongue wt 800. How much is this going to squat my pickup?

What is the GVWR, GCWR and GAWR (rear) of the truck?

The trailer has 15% on the hitch dry. What is the GVWR of the trailer? Mulitply that by .15 to get the weight on the hitch.

Load the truck like you will be towing with full fuel, DW, kids, bikes, grill, dog, etc and weigh it.

Take the rear GAWR, subtract 150 for the 5 wheel hitch, subtract the weight of the loaded truck rear axle and subract the calculated tongue weight. The negative number is the amount you exceed the rear capacity of the truck.

Do the same for the GVWR. Subtract the weight of the loaded weight of the truck and the tongue weight from the GVWR. Dont forget to subtract 150 lbs for the 5 wheel hitch. If the number is negative that is the amount you exceed the capacity of the truck.

we have a 2013 GMC with the same specs. tow 9600 max. we tow a 2013 fr micro lite 22' that weighs 3800 dry so we are towing approx. 4400 lbs gross with out a full water tank...GMC TOWS THE TRAILER FINE BUT I WOULD NOT TOW ANY TT OVER 5000LBS. The GMC would not be very comfortable over that weight. the 9600 lb max is in my opinion way over the GMC'S capacity and safety..Go to a 3/4 ton GMC...

To answer your question, a lot. You will offset this with a weight distributing hitch.

Unfortunately you will be overloaded. I have a similar spec Chevy and am touching max capacity with a 6500lb loaded Jayco 28bhs.

I towed a 22' 5,500 trailer with a 2011 F-150 with a 5.0 litre engine. A 1/2 ton truck will know the trailer is back there for sure. You will be overloaded with a trailer this size. For that size trailer you need a bigger truck.

Well, it looks to me from the RED highlighted info above that you provided, that right off the back you will be 275 lbs over before you put anything else (including you, passengers, equipment, etc) in or on the truck. Forget the towing capacity (9600 lbs), you're gonna be way over your payload capacity and probably your RAWR and maybe even you GVWR.
