The unit is a Dometic 13,500 btu AC with heat pump for colder weather.  The front 12V and florescent lights had to be move forward to provide space the AC unit. The roof was beefed up with steel L supports tied into the existing roof beams and framed with 2x6 lumber to support the inside control unit. A new electric box with circuit breaker was added to support the electrical needs and is connected to a second generator box on the outside to provide power.  Power is provided by a Honda 3000 watt generator.
