I still don't consider the back seats a comfortable place to be. Floor is very high, seatback is upright, and seat in front needs to be moved a long way forward to I can actually fit. (i'm 183cm tall).
That's weird. With my Dmax, with the passenger seat fully back, there's still plenty of legroom, but there's a thing about having the front seats that far back - I'm about the same height as you, and if the driver seat was fully back (and unlike most cars) my feet won't even reach the pedals. I slide the passenger seat back as far as it goes, and as soon as my SO gets in she slides it forward - there's so much room in front, surrounded by tacky textured plastic, that it feels exposed / uncomfortable.
Maybe you're just plain wrong about lack of space/comfort in the current range of twin-cab utes. I hate driving mine around town because it's so big, but on a long open-road trip it's fantastic:
there's tons of room.
As it's on a ladder chassis, there's very little road noise.
As it's high, there's less sense of speed / road blur.
On the highway with 4 px, it uses about 7.4l/100km.
I can chuck outboard motors etc in the back and not have to spend the trip sniffing petrol.
