It took some effort organising everything for 'camping mode' as during the trip my bags had sat on the bed and on the tiny bit of floor space in the back. I piled them up on the front seats to get them out of the way and make some space.
I made lunch mid-afternoon but this was a bit tricky. With the worktop full of laptop I had nowhere to make sandwiches. I ended up having to balance the bread on my knee to put the margarine on. At that point a tray might have been useful - and a plate definitely would have been. That's two more things on my 'must remember for next time' list.
At bedtime I played with the curtains a little and changed the way the front curtains overlap the side ones. This made them sit a lot better over each other and ruled out gapping. I used a couple of magnets on the sides of the back door windows to close the very small gaps here - these could be sewn into the edge of the curtain if I remember when I have a bit of spare time.
Getting changed in such a cramped space was actually much easier than I expected it to be. The difficulty was getting to what I needed and stashing the clothes I took off. All in all, between struggling to make a sandwich and fighting to find space for everything it quickly became clear that there isn't enough space inside to do everything.
Once I was settled in bed I was warm and comfortable right through the night. I woke at one point in the night and found it was quite cold out of bed, but wrapped in the quilt I was as snug as a bug in a rug.
