My converter is under bed as well. You should have a progressive dynamics PD9280A (80 amp). I know this as I had to change mine last year as it keep blowing fan fuse. As far as the switches, mine has a single rocker for block heater. They look like something to do with an inverter. The Jeanie in my option is the cats meow, as you always know what's happening with converter. Just don't forget to water batteries often if not sealed....
