Getting the sleepers off the roof rack on my own was a challenge, although it was easier the next day when my next door neighbour gave me a lift off with them

Before it was finished the daughter was playing in it

Not finished yet, I have some screw holes on the top to sand down and stain then make some kind of removable cover for it (got a tarpaulin for the short term)
It's got 34 bags of play sand in it so far (hopefully this will be enough)
