CAT Scale Numbers have me scratching my head
Loaded with TH Travel Trailer(36ft 9600lbs dry weight) and 1/2 gas
Steer Axle 4500lb
Drive Axle 5360lb
Trailer Axle 19080lb
Truck Alone with 1/2 Gas
Steer Axle 4900lb
Drive Axle 3360lb
I had no toys in the TH so I know the tongue weight is more then what it should be but 2,000lbs for a Toy Hauler TT? Educated guess is a little over 10,000lbs for total trailer weight right now(haven't weight it alone yet).
Next issue, my Chevrolet 2500 Duramax has a GAWR of 5200lbs on the front. I'm at 4500 loaded which is fine, but 4900lbs with just the truck? The truck did come with a ranch hand grille. 300lbs away from the max unloaded is tough to swallow. Throw my wife in and we are down to 150lbs left.

I have to ask, what exactly is your question? Those numbers seem pretty typical to me. Most 1/2 tons and many 3/4 tons are already close to their GVWR and/or axle ratings when fully equipped and with crew cabs.
Tongue weight of a typical hitch mount TT usually is much more than people expect. The further out from the axle the more the lever effect on rear axle weight. This is why load distributing hitches exist, they can make a huge difference.

maybe just shock. Never thought that the TH hitch weight would be close to 2,000lbs. Curious to see what 1,100bs of golf cart and bikes do the hitch weight. Just didn't realize we would be that close to max front GAWR just riding down the road

Typically from what I have read once you load your toys the hitch weight will actually go down a bit. Since empty weights are pretty useless you need to load up like your going on a trip, then drive over the scales.

This is correct but I don't think loading 1,100lbs will reduce the hitch weight from 19% down to the 12-13%, where I need to be.

or should I be looking at it like this
Gain 2,000lbs on the rear axle but lost 400lbs on the front axle for a hitch weight of around 1,600lbs?

With third grade arithmetic; I come up with a GCVW of 28,940 (Did you mis-label a number?)

So your truck weighs 8260 lbs.

May 3rd grader tells me the trailer weighs 20,680, so 10% would be over a ton.

Well, let me see, I bet your pick-up bed is centered over the rear axle. Just a guess, but I bet a third of the weight you put in front seat goes no back axle...

I figured there was a serious mistake in that post. Would you mind detailing info for your truck, such as model year, configuration (crew,single cab etc),2WDm 4WD? First 10 of the VIn would be great info. 19k is quite a bit of weight GCVWR depending on configuration. ALL I got was Duramax 2500.
Also, do you use a straight 2-1/4" ball hitch or a weight distributing setup?

LOL!
That changes the numbers, but not the arithmetic.
GCVW, 19080 subtract the GW of truck, 8260 (4900+3360) means trailer weighs 10,820 lbs. And a little more, 10820 (Trailer Gross)-9220 (trailer axle) gives a tongue weight of 1600 lbs. When you put the weight of toys in back of the trailer that will drop.

2012 Chevrolet 2500HD CC 4WD, 14K Equalizer WDH with sway. Also has rear Supersprings to help with leveling. 24,500LBS is the GCVWR

Are the numbers you posted while using the weight distribution bars? If you were using the bars, I'd think your numbers would be off.

IMHO, if your trailer was loaded to the max you would use it, I would say you need to tighten the WDH. The TW is still pulling 400 lbs off steer. Most of my life, if you loaded the truck you wanted part of that weight added to front. I understand that OEM have added a dotted fold line to the frames, which makes it harder to add TW to steering...
