Hey Jeff! The Coleman-Mach Signature Mach 3 can replace the old Dometic AC on your 5th wheel. Since these are new R32 units and that will be an old R410A AC complete replacement is required. You can choose from the following based on the color you want and if you have a ducted/ductless setup:

-Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Textured White # CM38RR

-Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Polished White # CM58RR

-Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Textured Black # CM48RR

-Coleman-Mach Signature Mach 3 RV AC System - Ductless - 13,500 Btu - Polished Black # CM98RR

-Coleman-Mach Signature Mach 3 RV AC System - Ducted - 13,500 Btu - Textured White # CM23RR

-Coleman-Mach Signature Mach 3 RV AC System - Ducted - 13,500 Btu - Polished White # CM83RR

-Coleman-Mach Signature Mach 3 RV AC System - Ducted - 13,500 Btu - Textured Black # CM35RR

-Coleman-Mach Signature Mach 3 RV AC System - Ducted - 13,500 Btu - Polished Black # CM55RR

Each one of these comes with the AC unit, air distribution box, and wall thermostat so you will have everything you need for installation.

What kind of 5th wheel do you have?

Hey thanks! It's an old Keystone, might be time to upgrade soon but for now I'll stick with the new AC cost over a new trailer.
