The big advantage a fifth wheel has over a bumper pull TT is simply physics. The pin sits directly over the pivot point of the truck, so there is zero "moment arm" magnifying the force of wind gusts. This makes the fifth wheel tow like a dream compared to a TT.
Yes, I know all about Hensley hitches, WDH's, etc. but they are all various and sundry ways to try to handle the physics that are working against the TT.
..You say you know about Hensley hitches, etc., but your statement after that suggests you do not.
A Hensley (or ProPride) does not 'handle the physics' as you suggest, its more like it changes the physics altogether.
You're talking about anti-sway devices (Dual cam, friction bars, Equalizer, etc). Entirely different animal from high end hitches like Hensley, ProPride or Pullrite.
The Hensley actually changes the physics of a TT and makes it nearly the same if not better than a 5er. Pivot point is projected forward close to rear axle, so it handles just like a 5er. Sooo, you get the towing physics similar to a 5er, but with a trailer that typically has a lower center of gravity (not as tall). Soo, actually, truth be told, a TT with a Hensley tows every bit as well as a 5th wheel, if not better due to lower center of gravity. Doesn't really cost anymore overall, either, when you consider the fact that 5ers typically cost several thousand more than a comparable TT.
Bottom line: With high end hitches like Hensley, ProPride, and Pullrite, towing stability is no longer a factor between the two. Either can tow solid as a rock now. The decision comes down to all the other factors already mentioned (floorplan, storage, use of pickup bed space, truck choice, etc).
