If you’re like me and see this lifestyle coming then you’re fortunate. You have a choice.

I could have paid rent where I’m at for another couple months. And when I left I would have been penniless. No gas money, no way to move my truck (leading to it being towed and me being without even that as a shelter), no clothes, no place to sleep, and so on.

But by leaving the nominal security of the place I’m living in now, I was able to decide what few items would make my homeless sojourn comfortable.

First I decided the height of my camper. The higher it is, the less gas efficient it is. The slower you need to drive, the more careful you need to be about parking when there are high winds. But, being able to sit up fully or stand up is a huge comfort factor both physically and emotionally.
When you become homeless it is important to not let your body language betray you. You need to appear confident, ready, and “normal”. This is even more important when you’re homeless because you don’t want predators thinking you’re an easy target. Being able to sit and/or stand tall is important. If you must slouch all the time in your habitat, it’s likely that the habit will follow you out of your habitat.
Because I am short it was possible for me to make my camper just high enough that I could stand up straight. I’ve never been so thankful that I’m short.

Second, I researched power. Our civilization is connected by electricity, the internet and cell phones. We work on computers, conduct business and pay bills on computers. But being homeless it was not likely I would have ready access to electricity.
So I invested in a solar panel and battery/inverter setup. I will need to be very careful with my power but I will be able to have a light and charging power for my small electronics.
I would love to be able to purchase another solar panel and battery in the future, maybe if I can find the occasional temp job I”ll be able to do so.
If you’re interested, I purchased the Goal Zero products. The solar panels and batteries are chainable. The batteries can be charged from the solar panel, an AC outlet, or by DC current (your car battery).

Being able to stand tall and have light. Those are the two most important comfort and safety items for me.

Yours may be different.
What were/would be the most important comfort items for you?
