something for rear ac?

[haus]

i need some ideas.

here's my problem... i need to build my blazer for an unknown environment. i don't know (when i get back to the states) if i'll be way up north, in the southwest, or anywhere in between - so think for worst case... also, this is the only vehicle i own in the states, so the whole family might be riding in it - also worst case.

i'm sure any ac setup would be fine for the front seats, but i need to get the back seat to cool off when i crank the air. what are y'all running for an a/c system? how well does it work? does it cool off the back at all? right now, i've got the normal ac ducting and interior stuff all there, but that's it. so you got a blank slate to draw on.

so here's the question, what would you like to have?
