The door should be motorized, idk if it is though. When they came out I saw a video on the truck from Doug Demuro and I think when it’s put in park the door from the cab to the cargo area automatically opens to save like a second per stop. So the side door could definitely have like a button you press when you get out to shut it while you walk away.

You should look I to Morphe now. Apparently main dev of ReVanced left and made it.
