I'm trying to get my head around in van electrics but dont understand the need for a jump starter!!!. I'm assuming the starter battery goes flat quite often then? Do you need one with a leisure battery set up??? I wasn't looking to get one, but do I need one.???
The starter battery shouldn't go flat unless you leave something switched on for a long time while the engine isn't running or there's an electrical fault. Or the battery is knackered.
A T6 is fundamentally no different to any other vehicle (unless it's been converted to be a camper), so it's no more likely to suffer a flat battery than any other car or van.
