Flew airplanes for about 43 years and found I just couldn't get away from using checklist. The list below is for a 30' Flying cloud, and not in order, I have an app on my iPhone that allows me to electronically check off before I ever move my rig. But you could change it up, print out and seal it in plastic. Hope it helps, may save an item from damage. Been there, done that.
