My bags are normally packed with stuff. In the winter I always carry my heated gear(paints, jacket liner, and gloves(Hotwired)). I carry a small tool bag with the basics, two small flashlights, rain gear, Gopro, cell phone. Depending on the length of my trip I may carry a sleeping-bag and hammock/tent. I never leave without my Gold Book. I'm really bad about carrying things I don't need. So occasionally I'll go through it and take out the things I don't use but then I end up putting other things in it's place! I am considering a airpump of some kind but I have never had a flat on the road... So, do I want the extra weight and lost space.... maybe! If someone comes up with a system to figure out the things that really need to go with you, I'm listening!
