Can one do car camping? and is it the same fee per night?

I'd call to make sure, but I saw rvs alongside tents, and there was plenty of space. Along with a museum, there is a shower house with bathroom, boat launch, and an awesome wildlife refuge.

Tent, car, and rv are allowed. Price depends on if you want electricity or not. A car with no electricity will be priced same as a tent with no electricity or rv with no electricity. The price increases with 30amp or 50amp services. Water is available at all electric locations and most primitive locations.
