Last summer I had a strange leak during a July trip. Hot, humid - AC ran wide open whole trip. Sunday morning we woke up to water dripping from the power jack on the front bunk.
Long story short, I did find some caulking cracks and have applied EternaBond to both front and rear seams. I have not found any additional water (although the inside ceiling shows some bubbling of the wood layer between the rubber membrane and the "wallpaper", on the ceiling. It appears to be dry and has not gotten any larger.)
When we camp here in the south, it is always hot and humid, causing a "lot" of AC condensation. Even when I park the camper with the 'front to rear' level, a whole bubble off level, it pools up quite a bit before it begins to run off. I haven't put a level on it, but I don't see a sag or 'low place' in the roof. Should I be concerned about the water building up? I'm hesitant to tilt the trailer even more.

The foam seal between the roof and A/C likely needs replacement by now is it has not yet been done since new. Make sure to remove the RV shroud on the roof and check all the drain holes in the pan amd clear any debris out first. You can try tightening down the 4 bolts that hold the RV to the rooftop...they are located in the ceiling air intake inside the rv. That might do it!
