aboard Nico.
Can I make a suggestion, if you are not in a hurry to have a dual battery system fitted, it may pay you to wait and get some advice on whether a DC/DC setup will be good for your vehicle.
At this time, none of the DC/DC suppliers know how to setup a system in vehicles with STOP/START and there could be some serious implications for your starting battery caused by using a DC/DC devices in these vehicles.
Just a suggestion.
