Thank you all for great response.
I would have loved to have those 2nd row seats to go back a bit since I have no use of the 3rd row and it seems that that space is really wasted cause 2nd row seats are fixed.
1) I guess other minivans (odyssey and sienna) have much bigger space in the 2nd row cause they move fore/aft. Any experience with those minivans? Is my thinking correct?
2) Pacifica hybrid 2nd row seats are completely different; they move fore/aft BUT are no longer Stow & go. That being said I guess if you leave the car seat on those then the 3rd row access will be restricted to some extend. What do you think?
