Got some more work done today. I completely covered the tail with coroplast and taped the seams using strips of self-adhesive vinyl. Should be pretty weather resistant.
I built a door/hatch/cover to get in to the cargo area. I added a lock to it, so I can have somewhat secure storage while away from the bike.
I still need to re-mount the chargers and build a seat!
The project is starting to look like something.
