I have been looking at another truck and was thinking how I would go about the build, I came to the conclusion that I would buy a fridge, a stove, a container for fresh water, one for grey water and a toilet of sorts, then build the rest around these items. When I started building the Kurbmaster I wasn't sure how it would turn out and how much I wanted to invest in it so I found an old heavy duty extension cord someone had tossed in the garbage on a site because the ends were trashed. I cut it in half ran one down one side the other down the other I installed one double plug at one end, I have enough cord to go out the window with a male end on it when I need to use it. I am planning on adding another plug on the end of the other side and joining it to the first one in an metal electrical box. All it really is is a fancy extension cord, no breakers, no expensive wiring, no fancy connectors, it did not cost me a thing, I scrounged all the parts. I only use it to plug my electric heater if I am somewhere where it is cold and have access to 110, I never plug in at campgrounds, I can plug the cord into my $14.00 75 watt converter to use my DVD player other wise all my stuff is 12 volt. If I was worried about a breaker I would buy one of those thingamajigs that has a breaker for using tools outside and plug my extension cord into it. I have monitored it and it has never gotten warm, even after running a heater all night long, so I am confident with this set up, five years on and I still haven't gotten around to installing the second plug.
