Days when humidity is high (summer or winter) my garage floor will be wet and my 2010 Mountaineer will have beads of water in the body but not always depends how high the humidity is. My concern are is moisture getting inside the running gear -frame-door and fender panels. Always garaged never driven in the winter. Just did front and rear differential fluid change and all looked good not milky. I see no water droplets in the oil dip stick. Your opinion would be appreciated.
