1000 km a day with WoWa

Hi I want to go to the Cote d’Azur in August, that’s about 1000 km. Can I do this in one day or should I plan for 2 days? My team is allowed to run 100 km/h in Germany, so that would be well over 10 hours, but in France you can drive faster, up to 130 km/h. Would you like to do this, or rather drive so long, or better put one between stop, if yes where? I drive over Saarbrücken. It’s my first holiday trip with WoWa that goes over 500 km t. I would be grateful for your opinions. Since my team is at the limit, the car is relatively light compared to the WoWa, I would hate to go over the 100 km/h. Greeting Steve
