help me understand tow rating's gvw gcwr gvwr
according to my owners manual and door jam and some googling I have come up with this
3.31 rear end
4x4 super cab 145" wheel base
8300 towing
gvwr 7200
payload 1650
gcwr 13200
max trailer 7800
curb weight +cargo + passengers = gvwr
gvw + loaded trailer = gcw
13200 - 7200 = 6000 , i feel like that should be the max trailer weight
my question's are, is the 500lbs difference between towing and max trailer for the tongue weight? if I have nothing in my bed, lets 650 between passengers fuel cargo could the extra 1000lbs be thought of as extra towing capabilities, I feel like that's a no but just checking.
is the difference in curb weight just the gvwr minus the payload

I understand the confusion. Here's how I approach the trailer / payload weight limit issue: GVWR, payload, GCWR, max trailer, etc. are various criteria for how much your truck can carry. You're limited by the FIRST one that runs out. In other words, which balloon pops first as you load up.
I don't quite agree with your rationale "13200 - 7200 = 6000 , i feel like that should be the max trailer weight." If your truck + passengers + payload is actually 7,200 pounds, then I agree that your max trailer weight is 6,000 pounds, from a GCWR perspective. However, if your actual truck + passengers + payload is less than 7,200 pounds, that leaves more trailer weight capacity.
As for the 500 lb advantage provided by the max towing package, that extra capacity is for whatever you want to use it for, whether it be payload or tongue weight.
If I have any of this wrong, someone please jump in and correct me.

Depends, you haven't provided enough information. You're below the max trailer limit, so you're fine on that ONE criteria. Now you have to check the rest.
Looking at your GCWR of 13,200, subtract 7,700 for your trailer (assuming that's what it actually weighs) and that leaves 5,500 pounds for your truck, including passengers and payload. I doubt your truck is that light loaded up. So the real way to look at this is to subtract your truck's loaded weight from 13,200 to get your trailer weight capacity. Again, that's JUST for the GCWR standpoint.
Payload: add up your passengers + cargo + trailer tongue weight. That needs to be below your truck's 1,650 pound payload capacity.
GVWR: Is the total weight of your truck, including passengers, cargo, tongue weight, below this limit?
If you want real accuracy, take your truck to a CAT scale with a full tank of gas and weight it. Then you can figure out the true payload and other towing related numbers.

Oh man. No wonder everyone hates 3.31 gears. They are next to worthless. I guess next time I'll know what to look for. I need to figure out what my truck weighs fully loaded and go from there. Only 7000lbs roughly is all it can tow
