Turning an empty steel box into somewhere I can live

I don't want to buy a finished RV. A bought RV is someone else's answer to "how should I live," and I want to answer that question myself. So I found an old cargo van and started from an empty steel box.

The constraints are the interesting part

• Power — where it comes from, how much I store, how many days it lasts.
• Water — how it gets in, how it gets out, how it doesn't freeze in winter.
• Space — how small a space one person can live in without it feeling like making do.

What's done

• The insulation and the wooden frame skeleton.
• A bed that folds up into a workbench.
• A storage drawer hidden under the entry step that I'm quietly proud of.

Why it's paused

I'm stuck on the electrical system, and I refuse to copy a standard plan off the internet — that would make the whole thing a successful replica of someone else's van. I want a design that fits how I actually use power. Rather than throwing in some setup just to look like I'm making progress, I'd rather stop here honestly and wait for the better answer.

Paused is not abandoned. Abandoned means never coming back; paused means it still holds a seat in my head. Cadence matters more than intensity. It will restart.
