I pick my new caravan up in a few weeks and it will be fitted with 12N + 12S plugs. My car is fitted with a single 13 pin socket so I guess it makes sense to ask my dealer to swap the caravan leads to the 13 pin type. Only snag I can think of is this; if I break down and need a recovery truck to take the caravan, will the truck be fitted with 12N/S or 13 pin? Or should I keep a 12N/S male to 13 pin female converter in the caravan, just in case? Will the breakdown truck carry one anyway?
