Not a Volkswagen, but definitely a classic vehicle: my 1971 Heimstolz LC 285 caravan trailer. Made by VEB Heimstolz Weferlingen in the former German Democratic Republic, this is a really traditionally-made caravan with a body made completely from wood. It isn’t very stylish from the outside, but the all-wood finish inside more than compensates for that. It’s nearing TÜV inspection, and it has been and will be used behind all three of my Volkswagens when going to VW meetings and similar occasions. It’s not really big and comfy enough to spend a real holiday in, but it does beat any tent.

Here’s a website about Weferlingen caravans, albeit in German.
