Just realized that I never posted an update to this. So for the bus freaks, here are some newer pictures, taken three months and 9000 kilometers later. Well, actually, the pictures were taken at the start of our holiday trip, so make that 5000 km.
As you can see, we removed the dark foil in the windows and replaced it with a nice set of curtains (Julia, thanks a lot for your help with this). And we also got old-style chrome hubcaps to replace the shabby black plastic ones with. On the inside, there’s now more room for stuff and a little gas stove.
