And about hitch extensions: no matter how strong it is, it still puts lots of extra leverage and unwanted weight transfer on the truck. Stretching the trailer tongue is physically and mechanically superior, it keeps the hitch closer to the rear axle.
The best towing trailers are goosenecks and 5th wheels, for precisely that reason.
The further behind the axle you put that hitch the worse the physics are.
They’re fine for lightweight trailers. The heavier the trailer, the worse an idea they are.
The reason everyone uses them is because it’s the only store-bought ready-made solution.
Stretching the trailer is custom work, there’s not a product they can sell you for that.
It isn’t better, it’s what you can buy at a store.
