Over the years I have added some "features" to my rig that get installed after I get set up. Over the years my memory of what I did during set up has also gotten fuzzy especially when in a hurry to break camp. So, I purchased some "Remove before flight" key chains and attached them to each "feature". They are easy to see when I do the walk around as I break camp. In addition, I have numbered them so I know 5 "features" were added at set up so I should have 5 at break down. These have saved my bacon more than once.
