Hey Mike, if you are wanting to replace the entire setup including the lower vent assembly you have now the Advent Air part # ADV95SR would be a great option for that. If you were wanting to just replace the upper unit and reuse your current lower vent assembly we don't have a solution for that since we don't carry Dometic and you'd have to go with an exact match replacement. Let me know which route you are looking to take.
