I have a 6000 BTU Mermaid cool only unit that I ordered by mistake. New,never installed, in the factory box. Left hand discharge, 120 volts ac. It does the forward cabin on our 36' classic. It comes with a manufacturers 5 year warranty that will be assigned to the new owner upon returning the warranty card. I paid $1500. Please make a reasonable offer. The unit is in the Philadelphia area.
