If the 'water' or condensation is dripping INSIDE the coach, it's usually because of a dirty air filter. What happens is the air cannot flow easily, thereby causing the A/C to freeze up. When the ice forms on the A/C fins, the unit struggles, the ice begins to melt and it flows inside your coach. Replace and/or clean all the filters and see if that helps.
If it's leaking OUTSIDE the coach, it's simply because of the increased humidity. All three of my units have a catch basin under them with hoses that run down and out the bottom of the coach. When we are parked on a concrete pad, I made some extra drains out of PVC to pull the water off the pad. You might get up on the roof and see what you have. If there's debris in the catch basin it will not allow the water to drain off correctly. As the water builds up, it releases and appears to be more than usual. Think flash flooding...only on a very tiny scale....Dennis
