First Real Bikepacking Trip Starting Sunday; Did I pack everything I need?

It's going to be a 3-week gravel trip across Germany (around 1,500 km) with two of my friends. We'll be staying in hostels or with relatives, so we’ll be able to share some gear — for example, medical supplies, which I haven’t included in the packing list.

Wish me luck! I think it’s going to be an amazing adventure — it’s our first big tour! 🙂
Any tips — whether for gear, route planning, or anything else — are very welcome :0
