Would anyone know if this same part will fit on a 2015 Chevy Tahoe. I have been trying to get a definitive answer for several weeks now and I am hoping that someone on here can help. We have not bought the vehicle yet and this is a deal breaker for us. The dealer has been no help and will not assist because they state that this is not an optional part for the vehicle. If anyone can help I would be very appreciative. Thank you.
