Power plug melted
Last week I was drawing close to the full 30 amps using the heat pump and a 1500 watt heater in my MH. A bit later I left the rig and for some reason checked my power plug. It was more than warm. Shut everything down and unplugged it to find a melted plug. Immediately went and ordered a new plug, replaced it today and being ever curious about causes of this kind of stuff, tore into the plug. Found an obviously bad crimp on the black wire which is the main power in. So, if any of you fellow campers happen to notice this kind of problem with your power cord, consider replacing it as you're in for trouble in the future.
