Motorsport venues with good camping?

[ajondyh]

Bought a MH and wondered which Motorsport venues would you recommend with good camping for motorhomes?

I have stayed a field next to croft for btcc and plenty pop up near Silverstone for events, we used dadford road camping. Donington has a campsite privately owned near by and oulton park has camping within the circuit.

You will find portaloos for the tenters but not much else facilities wise.
