No I didn't really have any sway from the jet ski. Scariest part of it being back there is that I can't physically see it. Otherwise it really pulled like it wasn't even there. I have done this combo a couple of times without any trouble. I do slow down a fair amount because I don't want to deal with passing traffic and switching lanes. I also am still working on dialing my hitch in and may need to find a different w/d sway hitch. What do you use?
