Thinking about getting one of these when they come out, or at least considering it. I have seen the inside pictures of the ext cab version of the 2015 Colorado/canyon - from what I understand they are the same seat design as the previous models. My question is, could you fit a car seat in those seats? A rear facing infant seat and regular car seat? I know the crew cab would be better obviously, I am just asking if it is POSSIBLE or if anybody has done this in their older Colorado or canyon? Just wondering. Thanks.
