Newell used 12.5kw gensets in their coaches until 1993 when larger generators started showing up. When Newell started building all electric coaches in 1994 (although there were still Newells built that carried propane for owners who didn't want to go all electric) gensets were typically 17.5kw to 20kw. I would think that most 12.5kw and larger gensets should be 240V. Even the 12.5kw generators sold by Home Depot have a 240 volt outlet on them. When you drop to about 10kw or less, they are typically only 120 volt.
