Why all the hate on 1/2 ton tvs

I understand that some 1/2 tons have a low payload but, I have two F 150 xlt's a 2010 and a 2014 with crew cab. 1 is a 4.6 v8 the other an ecoboost. They both have a payload of @1700 lbs.
That would be 500 lbs in the truck, and 13% tongue weight of a 9000lb trailer.
I don't want to try it, but it would be withing rating.
I previously had an 06 and a 94. All had about 1600 to 1700 lb payload.
No special equipment, not stripped down trucks, 2 were even the base v6.
I have to think the "extremely low" payloads are the exception as opposed to the norm.
My opinion FWIW.

Many people consider, not only what you can tow, but how much weight you can carry.
The loaded truck, with full fuel, people,dog, and the hitch, plus 12 to 15% of the loaded weight of the trailer, should not exceed the GCCW. Our 1/2 ton pick ups, fall short sometimes.
I am not one who believes that if you are rated to haul 1000#, that you can't get by with 1100#, but some are. Just my .02.
There will be someone else jump in soon.

Payload!! You will max out on payload well before the magical tow rating. Half ton trucks these days just don't have much payload. As low as 850lbs in some trucks.

If your trucks payload is say 1500lbs (on door sticker) and your tt has a tongue weight of 1k (using the average 13% of tt weight) then you only have 500lbs left for the family and any stuff you carry in the truck before you max out payload and GVWR, even though you are 2k under your tow rating.

You likely couldn't tow to that max 9600lbs rating either. Any weight in the truck other than driver (GM still not using new J2807 standard?)will reduce that number, and the tongue weight of a conventional tt would exceed the receiver rating. You might get away with a boat as they usually only have 5-8% tongue weights.

Tow rating is pretty much meaningless, and the last number that should be considered for towing.
