Duo-Therm Dometic A/C drain hole locations ?

[Manuel B]

My front unit has started dripping water inside, not from the seal but above that, does not leak in the rain, I have the original install/operating instructions but there is no mention of the location of the condensation drain holes, I have not removed the inside panel to see which exact unit I have but it's one of these:
610012.203
610015.203
610015.404
I've removed the outside cover and looked but it would be easier if I knew where to look, I've searched this forum and the Dometic site with no luck.

Sounds like the condensation pan drain hole is stopped up and overflowing into the floor or it has a crack and is leaking.

On my Coleman , after you take off the shroud you must take off the metal enclosure to see these holes. Hope this helps.
