Preventing condensation?

Granted, since we've arrived in the pacific Northwest, it has been rainy and wet every day; and cold at night. Knowing that condensation would be a problem with 2 humans and 2 dogs all sharing one small camper, I always leave a window and the vent cracked open.

But it RAINED (inside) on us one night when Ed bumped the overhead vent shut and I didn't know it. All we had open was the little window under the cabover - cracked open about 2". Clearly, it wasn't enough because every metal surface was dripping by the morning; the vinyl popup portion was damp; and there was water dripping from the overhead vent frame (I'm assuming from the metal vent casing?). I use an electric heater, so it doesn't add to the problem. (We don't have an A/C, although Ed would think I was insane to want it running with night temps in the 40's)

How much fresh air do you folks add to prevent condensation??
