Hey Keolaokalani, you can install a 15k BTU GE RV AC unit in your Coachman Catalina but you'll have to replace everything to do so with the part # GE44RR as just the top unit you mentioned is not compatible with the Dometic lower vent assembly you have now. There isn't a reliable way to mix and match AC unit upper and lower units is why.
