Since I left the GE badged 24" stack in the cabin, I'm getting the KM version for the trailer. The GE and WPool units use 240V allowing BOTH w and dry at the same time. The KM version is set up for 120V and requires that you choose EITHER w or d. Has anybody played around with one of these? There has to be a way to set the KM up for 240V. The owners manual makes no mention of it nor does the spec sheet.
