I noticed a lot of discussion on HaHa hitches and none on Pullrite. I have used a +/- 45 degree pullrite on my 2000 F250 Superduty crew cab since it was new. Pulled a 30 Airstream all over the country and never had any trouble with sway at all. Just wanted to let others know there are options to eliminating sway. HaHa looks a bit complicated to hitch up, but I've never used one.
