I'm new to having a TT, I've had a popup for 9 years, and just upgraded to a 33' TT. I only have one trip under my belt with the new camper, and I was surprised at how well it towed. I bought a Blue Ox hitch, and so far I'm happy.
On our first trip, we caught up with a guy pulling a utility trailer with a Harley on it, and he was getting wagged all over the road. The Harley had the back tire up against the back of the trailer, so I'm assuming little tongue weight, and the trailer was way nose up. He was towing with a full size pickup. Every time he got over probably 50 that little trailer would wag him all over the road. He would slow down, get things under control and try to speed up and the sway would come back.
I wish I had thought to video it, I never would have thought that light of a set up could sway a truck that bad.
