my trailer also has one of those power monger converters in it. the trailer is a '76 airstream 32'. the converter is much larger than a loaf of bread, and it pretty darn warm even if nothing is turned on. terribly inefficient!
my case is a little different as the trailer never moves, and no longer has batteries in it. i want to connect it to my RE system (24v), and have via the shore plug into the inverter, but it drains my batteries pretty hard over night. i'm pretty sure there are a ton of phantom loads in that thing...
so, just ordered a 120 to 12V 30A 360W Switch Power Supply Driver For LED, off ebay from china. lets hope it work for a whopping $29. thinking when i tear out the old one, i'm only gonna reconnect the wires that i need and hopefully end up with a more efficient converter that is no longer feeding any phantom loads. basically, i want it for is the lights, furnace, oven ignition, exhaust hood, and oven light. the bathroom has also been torn out and converted to a bedroom.
