I've tried everything I can to edit the xml and modDesc and can't get this to be universally attachable (I don't know what I'm forgetting now). Any chance you can share what you changed
Its not made to be universally attachable. but you can try changing the jointType name to skidSteer in the plow's XML. then it should be able to connect to other trucks that have the plow attacher available. from there, you will most likely have to make adjustments to the attacher joint in Giants Editor to accomadate the v-plow.
