As time went on, Simba became more and more of a mobile lounge. The wood-panelled walls became more and more covered in photos, lucky charms and souvenirs – and the perceived lack of space in the vehicle felt more and more normal. 'At the end of the trip, all other spaces felt too big, so I had to get used to that again first.' And saying goodbye to Simba – which after all was the first home the couple shared together – was very difficult for both of them. When they arrived in Munich after two years of traveling, they spent one last night in the Unimog. That was in October. Now Simba stands in a yard in Austria where, after all the rigours of the thousands of miles it has covered, it is being spruced up once again. 'We miss him a lot. Sometimes I'd so love to just get in, sit down and listen to the engine running.' Jennifer and Peter Glas have just one thing left to do: Dream about the next travel adventure in their Unimog.
