Bikepacking first trip starting in Marseille

hiya everyone been interested in bikepacking a while and saw this group a few weeks ago and it was useful so I thought I’d contribute 🙂
just started my first bikepacking journey yesterday in Marseille. Arrived by flight with one pannier bag packed with a few more and kept it really light with clothing.

When straight to meet Loulou who was selling bikes on Facebook marketplace and he sorted me with this beautiful orange Peugeot for 60 euros including lunch and WW2 stories.

I’m going to be going for 6 weeks and not 100% sure if the route but would be nice to get to Genoa and maybe further south in Italy. Just got a hammock and no plans to get a tent first night was surprisingly good.

Also considering going Marseille to Geneva if anyone has any insights
Questions
Any advice on camping that route from Marseille to Genoa
Is there an app people use to update people on their trips?
Any essential upgrades for the bike? was wondering if I need some beefier tyres?

Thanks
