Do you mean the personal possessions cover for things you take on holiday with you? And the cover for contents temporarily removed?
If so, we have that in our home contents, so do not insure the contents of our van with our caravan insurer (Caravan Club)
When we travel with caravan abroad, we always take the full Red Pennant cover, that does give some possessions cover, but if we are flying somewhere we do not take any extra cover.
