This thread is too funny! I would have never thought that mold would become an issue on any motor vehicle! Living in Phoenix and especially summer 112ºf heat can assure you that nothing organic will grow
I bet there are a number of spores that will reproduce - party hard, actually - in thermologically favorable conditions, then transition back into durable nodules when conditions are less favorable.
Life doesn't necessarily require a constant supply of water or other conditions that you and I prefer.
Take the
water bear: (yes, I know it's an animal, not a plant.... the thermophylic pseudomonas family creeps me out too much to talk about): Tardigrades can survive vacuum, high pressure, high radiation levels, no water, lots of water. Tardigrades are one of the more durable life forms that, very fortunately for us, is not interested in setting a water bear only zone on our bodies, or on our Sprinters.

PS: here's an exerpt from the wikipedia article:
Tardigrades are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of -273°C (-459 °F), close to absolute zero,[5] temperatures as high as 151 °C (303 °F), 1,000 times more radiation than other animals,[6] and almost a decade without water.[7] In September 2007, tardigrades were taken into low Earth orbit on the FOTON-M3 mission and for 10 days were exposed to the vacuum of space. After they were returned to Earth, it was discovered that many of them survived and laid eggs that hatched normally, making these the only animals known to be able to survive the vacuum of space.[8]
