Side-mount AC drain on travel trailer?

Most starcraft forums seemed to have a dead community so I'm here for the TW consensus. I have a Starcraft Ar-One with side mounted AC. I noticed it was dripping alone the base where the caulk wasnt done well and reapplied a layer around it, sealing it up and (so I thought) allowing it to drain through the slots made for that:





AC was running overnight and no drips out of those slots. I'm assuming there's some sort of tray under the unit to catch any condensation? I'm worried I'll go to tow it tomorrow and all that condensation is going to find a way into the wood interior of the camper.

 

Interested in what others say. Mine is a roof air unit, so I got nothing to offer.

All I know is that water needs to drain outside the RV.

 

I tried looking for some sort of drain pipe underneath but the only ones I saw were up front near the water heater
