At least the fridge will work

I am getting a tow bar fitted onto my lovely new Fiat 500X.  I thought it would be straightforward i.e. phone up, say I need a tow bar and arrange date and time.  No.  I was asked all sorts of complicated questions about electrics and the only question I could answer reliably was that I would have a fridge.  I have no idea what the fridge has to do with the tow bar nor do I know the difference between a single 7pin or 13pin socket.  I think it had something to do with the brake lights and indicators which obviously, I want to work.  The man is coming on Monday to fit a detachable tow bar and I am pretty sure he will have to show me a few times how to detach and attach.  I had a quick look on You Tube and it is not easy.

I have also booked myself onto a ‘Practical Caravanning Course’ for next weekend and extremely nervous about it.  It is advertised as both enjoyable and informative, lasts for ten hours and promises to have me full of confidence by day 2.  I need to check my car insurance is valid for these kind of things.
