I've just brought my 2007 Elnagh 640R home and this is going to sound daft but I can't find the leisure battery. I know it should have been pointed out to me on hand over but I thought how difficult can finding a ruddy great battery be. I've checked every conceivable place I can think of and I am baffled. The lights in the kitchen area come on without the mains hook up connected so there must be a battery somewhere. The wardrobe houses trip switches, battery charger, fuses, and 230v socket, but NO RUDDY BATTERY. Any ideas greatly appreciated.
