What items have you forgotten when you left for the winter?

We keep 3 list.
1. Things that need to be done in the house, like turn of water, cancel garbage pickup, etc.
2. Things that are already in the camper. We have acquired a lot of duplicate things like plates, coffee pot, camping chairs, etc. We keep this list so that we don't pack triplicates.
3. Things that need to be added. Like drugs, camera, hobby items, etc.
