Hi, Rusted, welcome to the forum. Greetings from central Kentucky. Congratulations on your Interstate purchase, looks really nice.
On the camera trick, make sure that if any of your battery powered devices get wet, never turn them on, take the battery out if possible. Wait for them to dry out. I've heard of the bag of rice trick but my preference is to take the battery out and if possible, open any compartment doors, then put it in front of a fan for at least an hour. Drying it out is the most important thing before trying to turn it on.
Hope you have many miles of adventures and fun traveling in the Interstate.
