Underdash, not integrated?

I put integrated in my WB PV and love it (thread on here)

I also put an underdash A/C in my Falcon XY (don't hate me) and while it's very cold, it takes away passenger foot space and freezes my GF's arse off - its fine if its just me in the car.
I'd go integrated every time

I did think of fitting an underdash A/C in the roof, blowing forward - wouldn't lose foot room I guess.
