Hi all hope someone can help I had my first away days in my Swift Charisma 535 2005 and loved it however the first problem I came across was that to have a useful awning light I had to run an extension from one of the 2 power sockets in the van out the door. Is it possible to put an external power socket on the outside and if so are there any instructions on doing this task like the one for fitting a heater switch in this month’s mag.
