i have a pull toyhauler and a equlizer set up. i was woundering if i still needed a sway bar to go with it?

Question

it is a 30 foot trailor im pulling it with a ford 250 super duty 4x4 about 6000 lbs for the trailor

Answer 1

A sway bar is designed to keep the truck level durring a turn, and will not affect the way the trailer rides.

Now if you put a camper on your truck, I'd upgrade the sway bar. But not for towing a trailer.
Just my opinion.
