Yes, in most cases this unit should replace the factory Dometic Brisk Air on a 2015 Grand Design Solitude 305RE, provided your current setup uses the standard 14" x 14" roof opening and a Dometic-compatible control system. The FreshJet 5 is designed to fit standard RV roof openings and can be used in both ducted and non-ducted applications. A few things to confirm/consider:
- Whether the existing AC is a Dometic Brisk Air, Brisk II, or Penguin/Penguin II model.
- Whether the coach is ducted or non-ducted.
- The type of thermostat/control box currently installed.
- The existing BTU rating (13.5K or 15K).
