It's dry here in Denver when we use the AC. I generally shut the compressor
off a few minutes before arriving someplace, so the coils dry out. No
problem.

I've been using cars with AC here since 1979 with no probs.

We have skunks down by the stream here, but rarely smell them when leaving or
coming home at night, because the small amount that does get in, with
recirculate, is sucked up by the cleaner.

Big truck engines have big crankcases which potentially hold more condensate
than a car engine. While the engine is warming up, the moisture in the
crankcase comes out the exhaust looking like white smoke.

Another possible cause of white smoke from a diesel is incorrect injector
pump timing. I am not current on diesel technology, but I would imagine
that injector pump timing issues are a thing of the past so my guess would
be moisture.
