I have neighbors that can supply any and all power to their doublewide with a diesel Lincoln Welder.
I have a friend who powers what he needs with a 250 Miller Bobcat.
I have firewood.
And an inverter that I hook to my truck.
I vote for the Lincoln.
Never thought about using a welder before.
Don’t forget to rig up an electric perimeter fence to keep out those pesky zombies.
