That is the reason I went with the powermaster, it is a 110 amp but puts
out 79amps at a shade above idle. Good point. I wanted something that
would take care of the dual spal fans with a 27 amp draw at idle when
they would most likely be need. heater/air cond. are a good source of amp
draw.. Ed ke6bnl
