Default Condensation Problem

OK, this weekend was the maiden voyage for our 2013 Montana 3582RL. We are camping in SW Florida and the temperature outdoors is just hitting 90 degrees.

We have the Dometic 15,000 running and the 13,500 running in the bedroom.

We first noticed some condensation at the ceiling vents. Later in the afternoon we notice a wet square on the ceiling approx 18 inches X 10 inches square just below the location of the 15,000 A/C unit.

When I say wet, I mean serious water that took a bunch of paper towels to absorb.

Today I bring our Montana home, plug it into our 30 amp and just run the 15,000 unit while unloading. Within a few short minutes we notice that same area getting wet again.

I get a ladder out, dry it off and notice that square area is COLD!! The rest of the ceiling in that area is warm to very warm, but that area is COLD. Thus the reason for the condensation.

Can anyone tell me why it would be cold there thus causing the condensation?

On my unit, that's right where the return vent is as well as the normally-blocked central high-output vent. What I'm thinking is that your setup is different, yet the A/C unit is still open at the bottom when it shouldn't be.

The only way to can access my A/C unit is from the roof. The ceiling covers the bottom portion.

Leemedic,
Sounds like you already know the problem, the 15K unit is not properly connected to the duct work. Since your unit is brand new, I'd be calling Lazydays for the repair! That way if you should develop a mold issue, the duct problem would be documented.
Best wishes,
