I saw one in the bay area Sunday, it absolutely had a distinct mud/baby-poop patina. Couldn't believe how much it stood out, how non-practical it appeared to be as a truck (I'd take a Rivian r1t any day for functional truck), and just how rusted it appeared to be (I thought it had driven through mud at first, but it was way too evenly dispersed), it couldn't have been a year old, or seen more than ten days rain.
