The White Hawk interior height is 6.5' and the Jay Flight is 6.75', I am 6.3' tall and found the difference very noticeable. This is clearly not an issue for everyone, but not bumping my head on the smoke detector and antenna crank is a plus!
Regarding the "structural issues", as I mentioned in my original post, the all three of the White Hawk 23MBHs we looked at when we were shopping (Winter 2015) had interior structural issues (deformed framing around bathroom door, issues with the Murphy bed, soft spots in the floor). I am not claiming that this is a pervasive issue with them, just stating fact based upon my experience.
Finally, the White Hawks do have comparably less cargo capacity compared to the Jay Flights (and SLXs). This means smaller holding tanks and less of a safety margin when loading the trailer with your gear. Compare the White Hawk 28DSBH (1385#) to the Jay Flight 28BHBE (2750#), there is a 50% reduction in cargo capacity.
One must take all of these things in account during the purchasing process. I decided on the Jay Flight over the SLX and White Hawk, but I am not claiming that this was the correct decision for everyone, just for me.

I am unaware of any "structural issues". We have towed the trailer from Seattle to Ohio last year and to Las Cruces NM and back this summer.
The Murphy Bed makes the White Hawk seem bigger than 20 feet. It weighs under 6000 pounds, if it were loaded. We do like it a bunch and I do not think we would go back to a heavy stick and metal rig.
