Okay,
I just received an e-mail from Adam Hunley at the factory. This is the Air Co going on my 2007 order placed on 11 September.
"The brand name is Colman and the model number is 9203-C876." Adam Hunley
I believe this is the Polar Mach system. See at http://www.rvcomfort.com/pdf_documents/polar_mach_ac.pdf#search='coleman%20air%20conditio ner%209203' or
