Bigfoot windows

X2 on the drain holes first

That would be my first thing before I do any more.

Ditto. Started seeing the inside wall at the back of the large dinette window was wet after a rain. Found the drainage path was clogged with dirt. Open the window and there is a sliding piece in the grove that drains out a hole covered with a rectangular piece on the outside of the window. You can try to blow it clean with one of those cans of compressed air used to clean keyboards but be ready for dirt (or mud if it's wet) to fly everywhere :B I'm not sure if this is where the moisture is coming from in the other locations but it's worth a try.

I had a problem with the pass through window on mine. It is pretty much useless, so I put a piece of black Gorilla tape down the joint onto both sides of the joint, and I haven't had any water come in there since. It means the window can't be opened, but how many times have you used that window?
The other thing that we do when travelling in the rain or dust is to keep the roof vents closed. I have Maxx Air vent covers on both and the aerodynamics want to create a vacuum in the camper, so water and dust come in all the little gaps.
