I need to be as organized as this. I probably have everything in that list in my storage areas in my Jeep but I certainly don't have a check list. I'm lucky I don't have to unload between trips, I just leave everything as is and if I used something, I replace it before putting the cover back over the Jeep.
What I didn't see in that list but I carry are spare tire stem valves and the stem insertion/removal tool, and spare rubber tire stems. You never know when something is going to tear a tire stem off. I also carry a 12" square of gasket material I can cut gaskets out of like for the thermostat housing. My thermostat stuck shut way up in the mountains so I had to remove it. The old gasket was shredded so I ended up cutting a new gasket out of a military MRE's cardboard box. Don't laugh, it was leak free for 6 weeks before I was able to get around to replacing it and the thermostat.
