As Ghetto said, see if someone local to you will let you try theirs out.
Comfort is a matter of perspective--a Mercedes these are not--luxury wasn't on Toyota's build sheet.
Long trips in any vehicle can become uncomfortable, and these are quite cramped.
That said, their are ways of increasing leg room with channel added to the seat bottom rails, padding can be removed from both the seat bottom cushion and/or back, TLC in Van Nuys swears by the BMW seats they use, other folks swear by the replacement seats they have retro-fitted.
I guess it all depends on how badly you want to drive one of these, and your version of comfort.
If you post your city/state, I'm certain one of the good people reading this will let you look at their truck.
Good luck !
