At a MINIMUM you need a basc WD hitch and TWO sway bars. One on either side of the trailer tongue. Again, this is at MINIMUM. I had a 31 ft 7000 lb trailer loaded and I had to run two sway bars. I had DC but had a serious ground clearance issue and couldn't use the DC system. However, your trailer EMPTY weighs more than mine did loaded.
I had thousands of miles pulling with two sway bars. And as I said before they are the MINIMUM I would use in your application. The Reese Dual Cam is a nice system, I also like the Blue Ox sway Pro design.
The dual sway bar plus WD is a set up I am very familiar with and don't feel unsafe with it.
Thanks and good luck.
