For stock cart values Look at version 1.0.1
There are two folders for this mod Cartkiller and CartFix. The CartFix mod changes the the Vehicle authority and adds a map marker. Instead of getting a deed it will link to the property claim. If the cart is placed on your own property it will get a new tab in the storage UI. If placed on a unclaimed land it will be a unowned cart and anyone can take it. If you do not have access to the property claim you will not be able to place the cart. Once you place the cart on owned propery the Auth tab will give you access to change the cart to public, white-list and Inherited. Public will not let other pick the cart up but it will let them use it.
The CartKiller Mod is so you can keep your same world. This will take out the authority all together. This is to unlock any and all carts and excavators in the world. It will give everyone access to the cart no matter where they are in the world. Once this has cleared the authority you can install the CartFix. This is a great way to clean up the server.
To Properly install CartFix on a current world you must first install the CartKiller start the server then save the server. after the save you can install the CartFix and restart the server.
