I am a staggeringly average 5'8" tall lol but my Hideout has probably nearly a foot over my head inside to the ceiling. And you get a full height bedroom as well in the TTs. I think the main benefits of the fifth wheels are cargo space (although you trade a truck bed for it pretty much), larger layouts, better to drive (as long as you know what to do when making a right turn
) with less sway or weight distribution concerns, and a nicer top end offering. They also can cost a lot more and weigh a lot more and are a fair bit taller in most cases. From a vehicle payload standpoint though, you will get a lot more out of your truck with a bumper pull vs a fifth wheel in terms of trailer. The highest hitch weights I have seen for TTs is about 1300# for the biggest baddest ones with 4 slides. Seeing trailers with a hitch weight of 700-900# is very common. That CANNOT be said of a fifth wheel.
