Weight distribution hitch required?

[GeneO]

I recently purchased a 2021 Sol Dawn trailer. I pull it with a 2017 Toyota 4Runner with a 5000 lb tow rating.
I am struggling with whether I need a weight distribution hitch. I have found that a WDH can bend the aluminum frame under certain conditions. Even Intech is not a supporter of WDH hitches.
I am told maybe add a sway control for safety.
The original owner did not use a WDH.
Does anyone have an opinion on this subject?
Thank you.

How much squat in the truck.

The truck hitch dropped app 3” with the trailer attached. I flipped the 2” drop receiver and ball over and now I am 20.5” ground to top of ball with the trailer connected .5” lower than the Intech spec of 21”. Before the flip I was 17” with the trailer connected.
