Yup.. Several guys on this forum use the little Honda 2000 inverter generator .. It can apparently start an air conditioner up to about 12000 BTU.. although some need a "hard start kit" installed on the air cond unit to get it to work.. If you get the EU 20000 i Companion, it even has a plllug that will fit your shore power cable.. but ya have the problem of safely carrying gasoline and making sure that the carbon monoxide doesn't blow into the cabin somehow.
