Our take on the Dometic Penguin II High Efficiency Air Conditioner

The Dometic Penguin II High Efficiency is a low-profile rooftop air conditioner for RVs, campers and travel trailers, rated at 11,000 Btu/h and drawing about 11.4 amps on 115 V. Its 11-1/4 inch height keeps it low on the roof, and vibration-dampening brackets are meant to keep it quiet. It suits owners of larger rigs who need a second unit or a replacement that runs efficiently on a 30-amp setup. Against bigger 13,500 and 15,000 Btu rooftop units it cools less but uses less power and sits lower; it needs a separate ceiling assembly to finish the install.

What reviewers say

  • 4.8 / 5917 ratings

Rated 4.8 out of 5 across 917 ratings, owners largely report strong cooling and quieter running than the unit it replaces. Complaints center on the separate ceiling assembly and the manual thermostat.

What people mention
  • CoolingPraisedOwners say it cools the rig quickly for an 11,000 Btu unit.
  • NoisePraisedReviewers report quieter operation than older rooftop units, helped by the vibration-dampening brackets.
  • InstallationMixedThe pre-installed gasket helps, but owners note the ceiling assembly must be bought separately to finish the job.
  • ThermostatCriticisedThe manual thermostat is seen as basic next to digital controls on rival units.
  • WeightCriticisedAt over 90 lbs, getting it onto the roof takes help.

About the Dometic Penguin II High Efficiency Air Conditioner

The Dometic Penguin II is an 11,000 BTU cool-only rooftop air conditioner for RVs, campers, travel trailers and motorhomes. It is a high-efficiency model that draws 11.4 total amps. It can run on a single 15-amp breaker, and in cooler conditions two units can run on a 30-amp breaker.

The unit stands 11-1/4 inches tall, a low profile that helps reduce wind resistance. It has a carbon steel base pan and vibration-dampening brackets for quiet operation. Its airflow design and high-efficiency compressor are meant to cool the interior quickly and evenly.

It can be installed ducted or non-ducted and fits a 14" x 14" vent opening. A roof compression gasket is pre-installed on the base to seal the unit against the RV roof. The ceiling assembly, thermostat and control board kit are sold separately.

Questions and answers

Does it come with a ceiling assembly?
No. The box has the rooftop unit with a pre-installed roof compression gasket. You need a compatible ceiling assembly for your configuration, sold separately.
Can it run on a 30-amp breaker?
Yes. It draws about 11.4 amps, and Dometic says a dual-unit setup can work on a 30-amp breaker in cooler climates.
Is it a heat pump too?
No. It is cool-only, so it does not heat the RV.
How does it compare with a 15,000 Btu unit?
It cools less but uses less power and sits lower on the roof. It fits larger rigs adding a second unit or owners who value efficiency over raw capacity.
What thermostat does it use?
A manual thermostat. There is no digital control on the unit itself.
What are its dimensions?
About 40-1/2 inches wide, 29 inches deep and 11-1/4 inches tall, weighing 92.61 lbs.
