Whether it's dodgy electrics, split fuel pipes or a badly installed cooker, there have been lots of reports of old campers catching fire. I have witnessed one going up in smoke (not mine) and it's really a sad thing when you consider how few there are of these classics left.
Nerds and anoraks amongst us will probably spot that the smoke seems to be coming from the air intakes on this one. Perished petrol pipes spring to mind here as the fire is more than likely to be in the engine bay.
Now where did I put that inspection lamp.....?
