Sway or not to sway

[chrislinck]

I have an HD2500 diesel to pull my 19 Bambi. Obviously way more tow vehicle than required. do I need anti sway or am I good without it considering the weight of my truck.
I have towed it locally and it tows just fine.

One day I pulled out of an RV park and forgot to tighten the anti sway bar when an 18 wheeler passed me going the other way - Believe me, it's worth the $100 +/-.

I have a one ton and use no WD, however I use two sway control units when towing my 30 footer. I would definitely use at least one sway control for your setup.
