I predict that Gen 6 4 Runner will either be what would have been called a Highlander TRD Off-road or a remake of the Fj Cruiser.
I hope I am wrong and we get the Toyota equivalent of the new Bronco.

The rust spot is at the bottom of the lift gate.
I believe it came from a leaking tail light or spoiler. When that happens the water runs down the inside of the gate and out of the hole. It is the only rust on the vehicle...
