I am going to buy a chevy tahoe and I want to buy a 3rd row seat. However the vehicle has a factory carpet covering the space where the 3rd seat would go. I tried to check to see if I could feel wells where the seat would go and I found 4. I just want to make sure without cutting the rug if the wells are there for the 3rd row seat. I was wondering if anyone knows if all the tahoes come with the well holes even if they do not have a 3rd row seat.
