I will probably use some tools/appliances with electric motors on my 320 Sundancer and wanted to know if the outlets are passthrough shore power or go through some type of inverter. The reason for this question was on my previous boat (1999 Mariah Z280) all the outlets went through the inverter. The problem was it did not produce true 60 cycle power so when I tried to use a small vacuum, it ran too slow to produce any suction. If the 320 is set up like this then I will have to get some type of 30 amp adapter for the shore power receptical to plug in a normal 120 volt plug on the power tool.
