Don't know what length you have, but mine is 35.5'.
I use your picture #1, but use double sway bars...no problem !
I tight them to the maximum I can go by hand, the trailer pulls nice & straight.... take them off for backing up.
Double sway bars is recommended on trailers over 25'
You need 12000 pounds torsion bars though.
My opinion & experience...others may say the opposite, but it works just good for me.
