Prefer Black Instead?

⭐ Up to $150 Dometic Rebate (April 1 - August 31)

This unit qualifies for up to a $150 rebate from Dometic when purchased between April 1 and August 31. See Dometic rebate submission guidelines for complete details.

⭐ Direct Penguin II Replacement — Same Height and Footprint

The FreshJet 5 is engineered as a drop-in replacement for the Dometic Penguin II:

  • Same 10.5" low-profile installed height as Penguin II
  • Same mounting footprint
  • No roof modifications required

This is the specifically-engineered path to modernize a Penguin II installation without cutting sheet metal or adjusting the roof envelope.

⚠️ Mechanical Cooling-Only Model

This FreshJet 5 is the mechanical cooling-only variant — no integrated heat pump. If you need integrated electric heating, consider the FreshJet 5 with Heat Pump variants instead. Additionally, being mechanical means it requires external control (thermostat and control kit sold separately, or reuse existing).

Compatible Control Components

Verified compatibility with these control components:

⭐ Up to 9dB Quieter (Interior Noise Reduction)

Upgraded motor and blower system: up to 9dB reduction in interior noise. Meaningful improvement over legacy Penguin II noise levels.

15,000 BTU High-Output Cooling

  • 15,000 BTU cooling capacity — fast, efficient temperature control
  • Reinforced steel base for long-term durability
  • Built-in hard start for dependable startup performance
  • Stronger airflow vs the 13.5K variant and legacy Penguin II

⭐ Built-In Hard Start

Standout reliability feature: built-in hard start improves startup performance and reduces the chance of tripping breakers when multiple appliances start simultaneously. Meaningful for RVs on 30-amp service or generator power.

Low-Profile 10.5" Height

Low-profile design gives improved roof clearance for low-clearance parking, garage storage, or driveway constraints — plus a more modern coach silhouette.

Ducted OR Non-Ducted Installation

Versatile installation flexibility — works with both ducted and non-ducted systems.

⭐ Pre-Installed Roof Compression Gasket

Comes with a pre-installed roof compression gasket on the base of the unit. This gasket provides the proper seal between the AC and RV roof — no additional sealant or roof gasket required. Simplifies installation and reduces the risk of installer-caused leaks.

Companion Components — Air Distribution Box + Thermostat

You may need to replace the air distribution box and/or thermostat control kit at the same time. We carry compatible options — chat or call for guidance if you need help selecting the right components.
