We insured our new Cali through the CC, (it seems to be a very good package). We had to join the CC to get the policy.
Whilst we are still very new to this life, we have used CC sites on about half a dozen times since. So far we have found the main CC sites to be excellent. They seem to be well organised, clean, quiet and well run and organised by friendly and helpfull people. The toilets, showers, washing up areas etc all seem to be just what you would wish for and more.
We use a Sainsbury's copper plated kettle with a built in whistle. Very snazzy! I did buy one of those Wacky practicals collapsible kettles but my other half poo-pooed it!
