Make sure you wire the 12s to be compatible with your caravan, there was a small change in the wiring in 1998.

daved's link is the older version (pre 98) Post 98 vans are slightly different wiring (basically pin2 blue is now spare as is pin 5 brown.)

Just fitted one to my vehicle ready for collecting our first van on Saturday.

On the 12 s plug thats on your caravan ( Grey plug) open it up and link  Pin 7 ( Black) to Pin 5 ( Brown) then earth the brown wire in the boot of your car.....this now gives you 2 earth wires to share the load..............Also, as pin 2 is now unused (though still probably connected to the split charge relay) the same can be done with the feed wire by linking pin 6 (Red) to pin 2.( Blue)......................................

The advantages are obvious. The combination of 2 cores is far better than 1  and the load (feed and return) is shared by 4 pins instead of two. There will be less voltage drop, less resistance and less heat build up. It is a relatively simple DIY alteration and is inexpensive......Plus your fridge will work while you are towing with no fear of pin 7 burn out!

I would recommend using 28/0.30 (17.5 amp) cable for the linking wires.
