I use to pull a boat without WDH and sway bars but it towed like you say, much different than a TT (box). I have had a 23ft and now a 30ft TT and I would not tow either one without a WDH and sway system. Even with an Equalizer system, I still have found some swat when passing or being passed by some trucks, not all. I am a stickler for safety when towing as I am not the only one on the road.I tow with a Ford F150 with tow package and feel very comfortable with my setup. Hope this helps, remember there is no substitute for experience.
