If your looking to get away from the crowds, that could be a tough one, Although this summer depending whats happening with travel restrictions it could be a quite one.
I would say your best option is the camp site in les vigneaux, https://www.campeole.com/camping/hautes-alpes/les-vaudois-les-vigneaux
Its two camp site the top one is a big one with a pool and bar etc, and the lower one is more rustic you camp in the trees and there are just toilet blocks, it has a really nice feel to it, and tends not to get to busy.
Another option is camping at puy st vincent http://www.campingpuysaintvincent.com/fr/ really amazing views and not busy, the down side is that is 15/20 drive down to l'Argentiere for climbing down the valley, but it is very close to grande brois etc. Its run by a very good Dutch climber and he's happy to help with good places to climb and whats new climbing wise in the area.
Have a look at those and let me know if you want more ideas.
cheers
