I will not be able to help you with Richtersveld, but here is some info. on Kgalagadi.
Maggie firstly, Kgalagadi and Richtersveld are very hot in the daytime during the months of November/December. Camping for more that two weeks in that heat might be quite exhausting
Camping at Twee Rivieren.
You get camping sites with and without power points Ã¢â‚¬â€œ so if you decide to camp, make sure that you make your reservation for the accommodation code CK6P (Camp site with power point)
Concerning the facilities:
If are camping you will have to provide your own cutlery and cooking utensils you can however try contacting Twee Rivieren via e-mail and ask if you can rent these utensils.
We have never camped in Kgalagadi, so I'm not sure if the communal kitchen has stoves.
