Hey Joe, welcome back! The Furrion Chill Cube Variable Speed part # FR57TQ that you referenced is designed to fit roof thicknesses between 1.5 inch and 2 inch so yours being 2.75 inch is not a problem at all and would not require any additional hardware or adapters. The only thing you need is an air box with the part # LC44DX and you'd be set but you would need this regardless of the roof thickness. What RV do you have and what AC unit are you replacing with this?

Please recheck the roof thickness requirement for the Furrion Chill Cube 18K, i think it requires a roof thickness of 3.5 to 6 inches. I have a Lance 1995 travel trailer (year 2020with a roof thickness of 2.75 inches
