Sorry for the delay on the fan information folks.
This is one of the best fans out there. Super quiet and moves a bunch of air.

To install I opened up the compartments on the side in the overhead shelf in the front of the Globetrotter.
I tested multiple sets of wires until I found an unused 12v then used that as the basis to install. (You could also tap into another set of existing wires if needed). The source/live wire was on the left side of the cabinet in my unit.
Drilled a small hole in the cabinet to thread the wire through. Mounted the bracket, wired the fan and then installed the set screw.
Super simple upgrade.
There is also a spare set of wires that were not hooked to anything that ran to the other side of the cabinet I used to power the other one but just as easily could have run my own wires with a fish line.
One thing of note is these fans need to be wired correctly with + and - to work so double check with a voltage meter to determine which of the wires you are tapping into are + and -
