Car Wash
I would think one without brushes would be ok, a touchless carwash. One with brushes will put marks on every panel of the truck. At the same time, the pressure from a carwash may knock off a panel, mess with something electrical or force water inside the cabin through some unforeseen panel gap somewhere. So, with that said, do it at your own risk knowing that something could happen.
Paint problems aside be cautious if you go to one that pulls it along a moving track. If you get out (and most prefer you do around here) it may put itself in park and the transmission could be damaged.
If you go to a drag-it-through style carwash you need to disable the auto-hold feature of the transmission. Otherwise when you put it into neutral the transmission will still hold. I believe the magic sequence is "Apply Brakes -> Pull Electronic Parking Brake lever to the release position" this will disable brake hold until the next engine restart.
