Question:
Hi, I have a 2006 Fleetwood Flair 33R with stock two A/C Coleman Mach 13,500BTU front, and 11,000BTU rear ducted system with 30 AMP system. I wuold like to upgrade the Front A/C by using the Dometic Penguin II 15,000BTU w/heat pump to help me handle the summer days here in Las Vegas Nevada with up to 118• F. Is that possible? Do I need a conversion kit to use my current wiring setup and thermostat? Can I also use the Dometic SmartStart for Penguin II Electronic Air Conditioner? Eventually in a later time I will replace the rear A/C unit. Thanks in advance for your help.

Hey Martin, thanks for reaching out!
You might be able to get the Penguin II # DMC98ZR to work, but Dometic has been weird with wiring compatibility so if you go this route, I recommend having a professional do the installation so you can have confidence it's done the right way. Dometic also says you need the Air Distribution # DMC66RR and Thermostat # DMC23ZR for a complete setup.
The Soft Start # DMC77RR will work as well, yes.
Let me know if you have any other questions!
