Hey Anthony,
The Furrion Chill Cube RV Air Conditioner # LC22BX requires a roof thickness of 3.5" to 6" according to the Furrion installation instructions.
Since your roof is less thick than this you'll need to install some bracing into your fiberglass. I'm attaching an installation video where Shane added some bracing to a Ford Transit in order to install the MaxxFan Deluxe # MA00-06200K that you can use as an example.
