The trailer sway as you know will vary depending on how balanced the load is in the CT. More weight behind the axles tends to create more sway. Too much weight up front can limit front wheel braking and handling on the tow vehicle. I have a 7*18 with a 2ft. V nose. It is a lot heavier now that I have built it out and with 64 gallons of fresh water, motorcycles and etc., I decided to go with a load balancing hitch and anti-sway bars. You can get these relatively inexpensively if you shop around. I can tell you, they made a huge difference in the handling and stability. You can't go wrong with that.
My trailer is 7.5ft tall also, so the side wind profile is larger. The sway bar and hitch again made a big difference when there are high cross winds. I can drive with confidence, whereas before, it was a "white knuckle" job. Highly recommended. At 65 to 70mph on the highway it is rock steady. The setup also improved the "pull and sway" caused by semi trucks passing by. It really does work.
