Eric is absolutely right.
Condensation is THE primary contributor to rust. It is not really a cause,
though. Bare metal is. You can have all the condensation in the world on an
epoxy-dipped piece of steel, and it won't rust for decades. Bare steel will
rust in minutes.
There are two types of condensation, one is caused by temperature, and Eric
described it perfectly. The other form of condensation is caused by Salts,
and brake fluid, which speed rust because they are hygroscopic, meaning: at
a molecular level, they attract H20, and keep it in contact with the steel.
You can fight both.
If you have neither the luxury of a garage, nor a second vehicle for use on
salty days, you still have many defenses. Undercoat everything on your van
with two coats of Kool Patch. Then, pull the interior, undercoat
everywhere, and spray all the seams and creases inside the van with 3M rust
preventative, Kroil, or Waxoil; all of which are thick waxy coatings which
seal out moisture. Seal 3-mil moisture barrier behind all panels.

OK, Here is what I have found to cause rust. Sorry to disagree
with all others on this, but some old guy told me this,....and it makes
good sense. Every 24 hours the day goes from hot/days to cold/nights.
This temperature change causes the air, (most nights, here in the
eastern USA) to become saturated with moisture. This Temperture/
humitity level is called the dew point. This moisture condenses
and becomes "dew" or water. The advantage this has, to rust your vehicle,
is that it is on the inside of your vehicle by way of the air. Its
in places the you cannot get to, after the vehicle was welded together
from the factory. The seams are a perfect example of this. This explains
why in the west vehicle don't rust as bad. At nights the air does not
get below the dew point as often.
So if you want your vehicle not to rust. Keep it in the garage
at night.
