You should get a generator... I have one for sale :]
Agree your cords, connectors, plugs etc would most likely melt first at the very least the plugs.agreed. I have also cleaned tons of mobile homes before and I use 3 5.7 vac motors and two are on a plug. and 1 and a pump are on another plug. I have never seen wiring melt. If I plug both accidently into the same circuit the breaker trips. no big deal, just flip it, relocate one of the plugs and I am in business.
