The receiver and hitch head weight is forward of the ball and reduces available tow vehicle payload. The bars and equipment of the hitch (frame clamps) mounted on the camper become part of the camper payload.
When talking GWVR the units are treated as two different vehicles (the maximum the tow vehicle can weigh and the maximum that the camper can weigh). These numbers are unique to the individual vehicles and are based on limits of the structure of the vehicle. (Frame loads, axles loads, suspension and wheel loads).
When talking combined weight limits, the limit is based on what the tow vehicle's drive train can PULL (not carry).
When I did my calculations, I took the combined maximum weight of the connected "rig" and subtracted the weight of the loaded camper (5400 pounds).
That left 5600 pounds of "pulling capacity" for the tow vehicle to weigh.
Since with a full tank of gas and a 150 pound driver, the truck weighs 4650 pounds "at the curb."
The GVWR of the Envoy is 6200 pounds. If we were putting sand into the envoy we could shovel 1550 pounds of sand in there as long as we did not try to tow anything.
Since the maximum the truck can weigh is 5600 pounds and pull a 5400 pound camper, the difference between the 5600 pounds and the 4650 pounds of curb weight is 950 pounds of available payload to remain under the Gross Combined weight.
When you finally connect the camper to the hitch, the camper STILL weighs 5400 pounds, just part of it has to be carried by the truck.
That tongue load has to come off of the available remaining payload of the Envoy.
That 650 pound tongue load has to be carried by the tow vehicle in addition to the hitch (and any other gear including family members) and still keep the total weight under 11,000 pounds and the GVWR of the Envoy.
So what I think you are saying is....
Since the 650 pounds is being transferred to the truck, it should not be counted as apart of the camper's load for determining Combined Weight.
If I subtract the tongue weight of the camper from the camper's weight.
5400 - 650 = 4750 then subtract THAT number from the 11,000 would allow the TV to weigh 6250 (50 pounds over its max).
So lets say we want to keep the GVWR at the 6200 pound max.
Subtract the curb weight 4650 - 1550 pounds payload
Subtract hitch 100 - 1450 pounds remaining
Subtract Tongue weight 650 pounds - 800 pounds payload remaining.
That does make quite a bit of difference and it does sound logical.
I need to think on this some more. Something is nagging at me and I can't get my head around it right now.
It is late and I am confusing myself.
