The truck is as cosy as it looks in the pictures, perhaps even more comfortable than the pictures can convey!
My friend and I did not get to meet Do during our stay, but Jodie was friendly and accommodating while showing us around their farm. The farm itself is pretty cool and the walking trail through the farm makes for a nice morning stroll as it will lead you to the resident chickens and geese and the vegetable patch. The compost toilet took a little bit of getting used to, but after the initial shock of seeing a gaping darkness where you would expect plumbing to be, it's pretty much the same as using a normal toilet (except you flush with woodchips!).
Other than that, I would recommend getting familiar with the location of the entrance to the farm if you're planning on returning after dark because it is very easy to miss it in the dark!
