Most manufacturers recommend using two friction sway bars on trailers over 26 feet in length.

What Barney said.
My trailer is similar size as yours and I pulled with only one sway bar for years and was happy with the setup. I was on a trip and encountered sustained high wind that was predicted for several more days. I bought the second sway bar and installed it at the campground. It really helped with high wind. I use both all the time now just out of habit. I would say if you have the hitch dialed in properly the sway control is just there for the extreme conditions.
