This mod provides with an alternative to getting your items back after death, somewhere in between Keep Inventory and those 5min item despawn times. This mod make your body drop on death and all you have to do is to find your old body to retrieve your stuff. The Carcass doesn't despawn if there's items in its inventory but it will turn to a skeleton after an hour, purely a cosmetic change.
Theres also a few config options to help tailor your experience, like who can access your carcass or not and if the carcass should despawn after a chosen amount of time.
