As far as I know, it never has to specifically state "do not use this truck," (although it should and that's something I should have requested that Aaron did when uploading considering I do that for literally all of my truck except the custom pack) but I'm pretty sure the rights of who can run a truck are with the owner of said truck period. I honestly don't want to argue, and I'm trying to be as respectful as I can, but no custom I have made for my use has ever been open, and I'd just prefer it that way.
