If you are in Washington State.. go to Lowe's (It's the sister to Home Depot but as far as I know... only Lowe's carries the products I'm talking about.)
Damp Rid makes several products. Some try to keep moisture out of the rig. But they make two sprays... MOLD RID and Mold Rid blocker and stain remover. One has a blue spray nozzle and the other has a red spray nozzle. They both are about the same... would do the same job for you.
Both are safe on skin and fabrics (but you should not put your face on a pillow sprayed with this stuff... It's smart to cover your mouth with a mask or scarf when you spray this around the trailer)
Spray the windows... spray the tracks at the bottom of the windows... spray the furniture... the floor, the corners of the closets... any pillows you can't wash... and any pillow cases and bedding that you can wash later.
Don't take mold or mildew lightly. It can make you sick.
Air out the rig.
Get to dry air.
Keep a window open and a fan going to get that humidity out of the rig.
Running a small air purifier/cleaner really is a SMART thing to do when you live around mold and mold spores. the NW this time of year is full of mold...
(Washington State motto is "The Evergreen State"... I'm thinking they are talking about mold... not just the trees.)
Taking Airborne twice a day for the next few days can't hurt.
