Semi truck pulling hitches

new to this game with the big trucks. Looks like everyone has their own personal 5th wheel adapter for the sled hook. whats a good configuration for it? what kind of material are we talking about?

Thanks guys trying to give it a go for next season. but need to gear up this winter.

Watch some of the videos of the PA posse trucks on youtube, the style they use is pretty effective at transfering weight. Mine is setup different and works for me, its just not as pretty.

Mine is made out of 4"x6" rectangle tube and is fairly thick, it used to be the main beam in a four row wide field cultivatior.
