if this debt was discharged, yes, they can come take the unit at any time. If you ride it or devalue it in any way, you could be held liable for that devaluation. Things don't happen overnight. Especially given the Thanksgiving holiday and the confusion it causes with the courts, mail, and businesses in general, they may not even be aware the BK has been discharged yet.
Have you tried calling them and asking when they are going to remove their property from your property?
