Yes, the Replacement Vent w/ Thermostat and Remote for Air Command Rooftop RV Air Conditioner - Non-Ducted Item # AT15021 is compatible with the Atwood Air Command Rooftop RV Air Conditioner - 11.3 Amps - 13,500 Btu - Ducted - White Item # AT15027-22.
It being ducted means the vent assembly doesn't have a shroud to direct the air through ceiling vents, only out of the vent assembly. The non-ducted vent assembly has a shroud that is installed prior to mounting the vent assembly to the ceiling. The shroud encloses the area where the air is pushed out from the ac unit so it only blows through the vents on the vent assembly. The wiring will be the same.
The thermostat will be on the vent assembly and not a wall mount. When installing vent assembly you want to make sure and use an insulation tape around the inside edges between the ceiling and roof to seal all open areas into the roof cavity. This will maximize the amount of air flow coming from the unit into the camper and not allow any air to escape into the roof cavity.
