Before I advise. I hope you didn't just turn off ac and packed up and travel down the road and noticed water... I have seen several types of leaks. 1 was because the unit wasn't level tilting forward with drainage blocked. Another one had to figure out how the cond fan was splashing water around. (Old unit). (Had foam loose that was siphoning like a wick to blow water to front of unit)? Or, (someone exchanged AC units inadvertently put cutoff foam on it when shroud was off and forgot to removed foam). Took 6 times to figure that one out. Had to be someone put foam up there to try to quiet unit somewhat maybe. Used RV. When you by these used RV's. You do not know what the hell was done before you buy it.
