The electrical system in a caravan should be checked regularly. Because a caravan is constantly on the move it is possible for connections to come loose due to vibrations. If the van or camper trailer is a pre-owned unit it should be inspected to ensure that fittings are of the type approved for caravan use.
The possibility of a fire in a caravan or camper is generally very remote, but it should not be ignored. Consider the caravan or camper you own or are thinking of buying. There are numerous gas lines, gas cylinders, gas appliances, electrical fittings and flammable materials.
