Well Psadave46 your post does not contain much info (clues) such as A/C model and where it is leaking from so all I can do is guess that you have the usual Atwood AirCommand AC1511 Heat Pump issue.
If that is the case I thought I had the same problem. However, it is a design issue and it is being addressed by Dometic. So for now, clean the filter and the “leak” will stop for a few days. More info is available here:
