A mixture of 12V from a leisure battery and 230V for when there is a 230V hook up. Inverters?
Caravans are IMHO just things that I normally queue behind on the A64 or overtake if I get a chance.
This one is in Bristol and needs a rewire. So apart from hogging the middle lane of the M5 on my way to get to Britol do any caravanners have any tips on the best way to do caravan electrics?
