Lots of rain this week. Staying inside during rainy weekend camping trip in "Paradise" MI water started dripping from the ceiling!! Unscrewed fascia of A/C and found leak. A/C is set on a foam ring and long bolts are run up through an inside frame to a/c and tightened up to make seal. 2 bolts were quite loose. A few turns later and the leak was fixed. Whew that was almost a disaster. After a good shakedown cruise it couldn't hurt to check this.
