This Kawasaki weighs 1900lbs and my octane T31b pulls fine. I haven't had any issues with sway pulling with my Ram 2500 and an equalizer hitch. It does seem like the wheels are back a little farther than they would be on a normal travel trailer but I don't know for a fact.
It's a tight fit and it would be nice to have the bigger garage of a fifth wheel but this gets the job done for me without having to get a $100,000 20,000lb monstrosity. Plus like you I am able to keep a topper on my pickup.
