Hello boys and girls.

Got it. Local earth stake to body bonded to ground terminal of feed from panel to field. GFI is for school girls.

Later: (lol), the issues of carbon steel stake, copper wire, and aluminum van body. Isn't engineering awesome?

Ian.M:
No, a GFCI is essential because you don't know what the resistance of the ground stake will be, in possibly frozen ground.  If it too high a fault to ground may not trip the breaker, then you could die entering or leaving the vehicle.

Don't worry about electrolytic corrosion as long as you dont let the snow build up against the wheels or under the chassis, and you've used Noalox or dialectric grease to keep moisture out of connections between dissimilar metals.   The ground stake to ground wire connection should be sealed with self-amalgamating tape, then put a pop can over it to keep the weather out.

OTOH if you cant prevent snowdrifts building up to the vehicle body, you are in for a world of grief and should probably get an isolating transformer so you can tie Neutral to chassis on its secondary side to prevent stray currents from mains equipment eating holes in the bodywork.

(Thanks for the quote hand hold :))

Good point. The relatively skinny and long run out with (3 total) interconnects might not even pop a 15A breaker hot to neutral short.

I have a "scrap network" that I've put it out to that I'm looking for 200 feet of 8/3 (so I can run my hobby Lincoln in my bus project next year), but with much on the go and the back of the van an interim "mistress bench" there's not ten dollars to invest.

Still, might as well do it more or less right. Though this might be a first.

Frost hasn't set in yet though the days are short .. today going to mig a fireplace poker to a bit of discarded bus crossmember and get it down in the muskeg before work.
