Roof ac condensation

Anyone notice water from roof ac running down on exterior of Sprinter. I just noticed water flow while parked and roof ac running. I had not thought of where any condensation may exit the unit. Very hot humid air in S. Louisiana at this time. May have something to do with water condensation
buildup. Any comments?

It's normal. If parked headed downhill, it will usually run down the A-pillar. If parked headed downhill, it will usually run down a rear corner. My salesman told me about it during the orientation.

The higher the humidity, the more the A/C will extract from the air as it flows across the evaporator. Same as the A-coil in your furnace at home that usually runs down a tube to the closest floor drain.

Glass half full or half empty to an engineer is simply a glass that was over designed.

PM me for sale info on my 2011. SOLD!

Agree it's normal. I sometime run the AC when parked in my driveway with slight nose up incline. Then the condensation runs down the back corner of the van.
