My husband and I are about to take delivery of a new Bailey Ranger, and we are totally new to caravanning. We are confused about 2 things. 1. Electrics. We are having a detachable towbar fitted with a twin socket which I understand allows us to power the van's appliances whilst on the road. However car is 12V and site is 240V ? Dont understand how the van can run off both 12 and 240 and do we use ordinary TV, microwave, VCR etc ? 2. Does anyone know whether fitting a wheelclamp such as Bulldog QD44 would interfere with the levellers (ramps) we may use on uneven sites. The QD44 looks as though it might not work if we are using levellers. Hope I have made myself clear..!
