Posting a lot lately but really trying to narrow things down in our search! Whatever van we end up with, the plan is to move the 2nd row captains chair toward the center- make sense? So my question is this....obviously I can only use the latch for up to so many lbs. so what happens when I need to use the seatbelt for that seat? Depending on the van, is the seatbelt attached to the body of the car or the seat itself? How does this affect carseat installs when moving the captain seat toward center? It's hard to tell in the pictures how the seatbelts are. We are looking at Siennas, Odysseys, and now may have tossed the town & country into the mix if that makes any difference based on make. I know I am probably over analyzing everything but I just don't want any surprises or regrets down the road!
