We've just been followed on twitter by @BosCamping who sell what looks like a really neat collapsable fire pit.
From the pictures it looks a sturdy design that will collapse flat, which I guess means it can be easily cleaned as well.
Anyway, it made me feel a little warmer on this very chilly day.
I've decided to try and sort the electrics in the trailer tent out. At the moment we have a standard EHU cable which clips to one of the poles in the awning which is fine but we end up with lots of things balanced on top of it while they charge up. So I thought it would be useful to have power in the trailer tent itself where there are flat surfaces to put things on.
