Water coming from ceiling AC vents

Out on the road in the midst of Harvey reminants - warm, humid and rainy. In AM shut down AC units to prepare to move. They were off maybe 30-45 min when we started to move (body roll was decent on this unlevel road) and for some reason 1/2 to 1 cup of water each came out of the front, center, and rear ceiling ducts. Ideas? I'm thinking the coils had frosted and the ice/water hadn't drained yet.

You might check to see if the drain is open. The pan might be full enough that the water sloshed out.

We were at Hunting Island State Park last week and it was very very humid. One evening I noticed a bit of a drip ( small stream for a second or two ) coming from the rear most vent. I had seen this one time before from a different vent but under similar weather conditions.

Need to check the drain holes of your AC for possibly plugged drain holes.

Been up on the roof and all drain hole are open and dripping just fine. Oddly however (and likely unrelated) I've got puddles of water up against the outside gutter line under the upper awning rails. I'm going to level and then dip one of the ends of the coach down a bubble or two in the future. This caused the puddles to drain off rapidly.

Phil, I had the same issue. Tech at Newmar found during ourblast warrenty stop that we had an AC to roof seal that was crimped during install. He replaced, took coach to water test facility and problem solved.
