While not quite as nice as moisture sensors, this is possible and I have installed a few of these before. When doors are locked via a key fob, power windows can be actuated to roll up. These can also be activated on a timer so that something like 90 seconds after the engine turns off, the doors will lock, windows will roll up (and sunroof will close), and alarm will arm. Pretty slick!
As for the moisture impacting electronics in your truck based on those pics, you should be fine.....I've seen much worse with rain.
