Stock tool bag, plus
Digital tire pressure guage
4 way screwdriver
I also keep some fuses and bulbs in a custom cut chunk of foam that lives in the main backbone tube.
After looking at what other people carry, I'm going to add the 90 degree tire valve extender.
Squish, why do you not use the tool box? My /5 box is fine with 37 years and 200k plus, and my '95 PD box is fine at 70,000 miles. I agree about the sidecovers though. My RS sidecovers will reside on a shelf until I decide to sell it.
