Air Conditioner Drain tubes

[Don Bradner]

Until last Saturday I had only run the air conditioners in dry conditions. On
Saturday in Bakersfield it was humid, and when running the middle air
conditioner it began to drain water inside the coach.

I got up there today and removed the covers, and poured some water in the
drains. It drained, but very slowly, and there was no sign of water anywhere on
the ground around the coach.

So, two questions: Where do the drains go (I got out a mirror and the only
drains I can find are at the very front, presumably for the engine-driven air),
and what tips for unclogging them?
