I have several lists. One list is stock I normally keep in the trailer. I occasionally use it to check my supplies of stuff in the trailer. I have a list of stuff to bring for regular camping trips, stuff like food items, clothing, etc. These are things that normally do not stay in the trailer and get packed each time. I have another list for when we go to Florida for the winter with the trailer, because there are certain things we take then that we don't for shorter trips. I also have a hitching up check list of everything to do when we get ready to go. These include stowing all loose items, putting a bungee cord around a couple of cabinet doors, putting the rods in the fridge to keep stuff on the shelves, etc.
None of these lists ever see a piece of paper. They are on my iPad, and I check things off as I go, then delete the annotated version, leaving the original intact. (I use an app called Goodreader).
