Hi Warren; since you have a Dometic setup the Advent Air Replacement RV Air Conditioner for Dometic Setup # ACDOM135 will work as a replacement. This will be a plug and play installation. If you would like a 15,000 Btu unit we also have the # ACDOM150. If you need a heat strip, the Electric Heat Strip for Advent Air RV Air Conditioners # ACMHD is sold separately.

Hey Warren, how did the Advent Air replacement work out for your Chinook Concorse? Did the plug and play setup go smoothly? Your update could make it easier for others replacing their old Duo-Therm units.
