It depends on time of year.

I live in my RV. I actually have more power than I need (solar). But water supplies are limited, and so is propane.

So the poll says "you have water".

But when the propane runs out, no cooking (I can eat a lot without having to cook it), BUT...if it's REALLY cold out, I'm screwed.

FYI, I use to live in brick and stick house, and I was prepped very well. I could maybe go a year or more if I had water. Since I'm in an RV, I said 1 Month.

Still need to plan and stock my long-term stores v

I voted 90 days, I have a basic house on a small suburban block. I have onsite power generation and ground water plus filtration, so they are covered. I adjoin 900 acres of wetland, I know all the edible plants and have a map showing where the good ones are. But I would have to leave my house.

I've spent a lot of the last month traveling and don't have much at the house as a result.

But I just got sandwiches delivered so maybe now I could go 2-3 days without having to eat one of my roommates...

I had to vote for 4-6 months because my canned goods and freezer goods are low right now. They will be built back up after the summer growing season again.
