Just to mess you up even more, all AWD drives are not the same. e.g. Suburu's AWD system is different from Honda's.
I just replaced our Acura RDX with a Lexus RX. In Canada, both of these vehicles come standard with AWD so you don't get a choice here. In the USA, FWD is standard.
I refrained from commenting in this thread since it didn't seem limited to trucks but since it's still here...
