Nah, I’ll just buy a genset…batteries are a pain, expensive and ad lots of weight. Perfect for a remote Alaska cabin, however – that’s what everyone does off the grid.
I’m thinking an Onan or Generac system, the kind in the box – reasonably quiet, low RPM compared to the one-cylinder portables, and extremely durable. I’ve seen a number of the new mobile kitchen builders installing these on extended trailer tongues. I’m guessing I could have a local welder do the same setup for me.
