Question:
I have a dometic ac I'm looking to replace on 2012 5th wheel. It was a 13.5 and I would like to stick with the same. Will this work as a replacement?

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

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.
