which is better structurally
Which is better for what? The truck or the trailer. I would go with a longer tongue for the trailer if all other things were equal. If you extend the tongue of the trailer be certain that the tongue extension can handle the trailer's weight. Otherwise there is always Torklift that makes a truck receiver and an extension that is strong and works.
I just went through this.With an extension you will lose approximately 50% of rated hitch numbers,with a hitch ball with a longer shank,you lose nothing in rated capacities..Example from e-trailer for a 12" hitch/ball
(4285 Draw-Tite Ball Mount for 2" Hitches - 3" Rise, 4" Drop - 12" Long - 12,000 lbs)..
I ended up getting an extension because My ATV trailer is only rated for 2,000 pounds and the hitch extension is rated at 350/3500 pounds which works for my application.If I got a larger trailer I would have to go with the hitch ball setup at 16" long for 6,000 pounds.
