I have a 2004 360 Sundancer. The AC unit under the front bed is filling the front bilge in the floor.  Every time I takeoff the floor gets wet where the edge of the bed is. 

i’m guessing there must be a plugged drain somewhere but don’t know where to look  Is there a hose that goes from there to the shower sump?

See if the pan under the AC Has a crack near where the drain hose attaches to it. I had the same problem. I couldn’t get the AC unit out but was able to move it to get to the connection mix’s up some marine tex epoxy and sealed around the drain connection , that stopped the leak.

Also, try running hot water with bleach through the drain line. (This should be done on all drains occasionally ) I reversed a shop vac and blew air through the drain line to clear mine.

I have a 2010 390 that had water leaking from the ac unit. After making sure the drain hose was clean, it still drained onto the floor. I had so much condensation and the ac unit was installed at an angle that the condensation would drip off the side of the unit as it was mounted right to the edge of the pan. Since my pan was rusting out anyway, I installed a plastic pan under the entire unit and it still working 4 years later. If this is your problem you can find my post by searching "cbruck" and towards the bottom there is a post with pics etc showing how to install another pan.
