Truma Aventa A/C drip

[Against The Wind]

Hello friends, have a situation that calls for your expert advice and knowledge. While camping at Stone Mountain Park near Atlanta this past week, we developed a drip from Truma a/c inside the cabin that we found disturbing. A slow drip from the knob that adjusts the front to rear airflow ( probably the low point) plagued us the last 3-4 days of our trip. Now, Atlanta in July is not the most hospitable place on the map with temps in the upper 90’s and humidity way above normal human levels, but after having factory service earlier this Spring, we figured all would be well. We were near level in our camping spot and very shady however,I did not see a lot of condensation dripping from our condensate hoses at the rear corners of the camper. I did notice some condensation running down the back of the camper so, does this point to a clogged drain hose? Is this something I can fix maybe by blowing air up the drain hose? Should I seek factory help? Should I stay outa Georgia in July? As always your knowledge and response is most coveted  Thanks in advance.
