When is a 3/4 ton needed?

As in actual payload numbers being 1000 and 1500lbs, yes you’re correct.
But with respect to the vehicles construction and components, they are night and day with really the only carryover between the models being possibly 1 engine option and typically just ancillary components like interiors or sheet metal. And even that is different in a lot of cases.
The meat and potatoes of each are nothing alike. But nice justification for your heavy half ton.

I didn't say there wasn't a difference between models, just that the NOMENCLATURE 1/2 ton (1000 lbs), and 3/4 ton (1500 lbs), doesn't have any real meaning anymore.

Here's one article that discusses this topic. Be sure to read the "Now the confusing part".

If you look at an old 1/2 ton truck, and look under a newer F150, the first thing you'll see is that massive frame, huge springs, large 4 wheel disc brakes. But, same classification... to some.

My buddy bought a Chrysler truck, with coil springs, and had issues with bed sag, and hobby-horsing when towing. FWIW, he also had a 25' TT, but nothing in the bed of his truck. He had airbags installed, still didn't like the setup, sold the truck and trailer. It was a common complaint, hence why I recommend checking out the vehicle forums!

This is why I say trucks in the SAME pseudo category are NOT built the same. I spent a lot of time researching, talking to actual owners, test driving, and climbing under all the trucks. I have 106K on my truck so far. Very satisfied with my purchase. But some will still believe trucks can't or shouldn't tow within the manufacturer's specs... unless it's a dually diesel.
