I swapped out the Brisk Air II's in my previous toy hauler with Atwood Air Command units. They are much quieter and provide colder air. I was so impressed with the Atwoods that immediately after upgrading to a new toy hauler I pulled off the (brand new) Dometic Brisk Airs and installed Atwood units on that one as well.
The Atwoods also draw less current. I put a meter on both the Dometic and Atwood while they were both sitting in my garage and the Atwood pulled about three Amps less.
The down side of the ducted style Atwood unit is that it uses an electronic thermostat with a flat cable like used on a phone. I used RJ45 punch down blocks at each end of the old Dometic thermostat wire, shortened the Atwood cable crimping on new connectors, then plugging into that. You can find everything required at Home Depot though.
