for our first, yes, I would put him in the front seat, with a rear facing child seat, and turn the airbag off whenever he was in there.
with our 2nd, I once tired to put him in the back, with a rear facing child seat, and it just would not fit at all..the seat was only half supported by the seat, the rest was hanging off into nothing, then the front seat had to be so far forward that it was unusable for a passenger.
now, with my oldest being in the little jump seat/booster thingy, I just toss it in the back and he sits on it, uses the regular seat belt, and has no problems at all.
I never did try a front facing child seat in the back.
how old are your kids? if they're past the rear facing seat days, then you could possibly get away with just a club cab...until they turn 10, then they won't fit back there at all.
