We're looking at a new Tahoe with the 2nd row bench seat. Our biggest concern is access to the 3rd row with a car seat installed in the 2nd row. Do the bench seats slide forward on a track system, which will enable us to keep the car seat installed, or do they pivot forward? We will have a car seat on both sides of the 2nd row so this is a kind of make or break for us with the Tahoe. Thanks.
