Adding a Third Air Conditioner

On last summer’s trip, we suffered in hot locations, when even our two air conditioners were insufficient to keep the RV interior cool.  I decided to install a third generator.  The living room has a ceiling fan installed in a recessed bezel, so there’s already a hole in the interior ceiling and a 120-volt line (see stock photo below):

I removed the ceiling fan and its mounting bezel.  I then drilled four holes in the corners of the interior ceiling hole so I could identify the corresponding location on the exterior roof.  Up on the roof, I found the four holes and cut away the roof’s rubber membrane:

I then cut out the roof section, revealing the interior below:

The air conditioning unit mounts to the roof, and the air distribution module mounts to the interior ceiling:

All done:

To run all three air conditioners while driveway camping, I removed the three air conditioners’ power connections from the breaker panel and assigned an external extension cord to each air conditioner (see here for details on why this is necessary).  We then tested our new monster generator with the three air conditioners:

The generator was able to handle to load without issue.  Looks like this summer’s trip will be much more comfortable than last summer!
