Hi Carol and Pete
I agree wholeheartedly with Peter.
Mayday from the Caravan club gets you breakdown service from Green Flag, and it is a cracking deal. Read up on it in their brochure, or in the Club literature - it is by far the best cover you can have in the UK, and a Great Price right now.
Red Pennant from the Club is the one for travel abroad, once again - complete peace of mind in any event is just a phonecall away. You can choose the motoring part of the policy if you prefer (you already have personal insurance), or both motoring and personal.
Have a wonderful holiday
Kind regards
James
