not sure where to put this so I'm going here. My ac is leaking water after running in the heat for a long time. assuming the drain is blocked. I will be getting up there this week to clean things out ...
Assuming the AC is leaking on inside of RV, the likely culprit is clogged drain pan.
If your a DIY kinda person you can get up on the roof and remove the AC shroud and inspect the drain holes around the pan for blockage and clean as necessary.
Also inspect for cracked seals while your up there.
