A couple things...
My bed is simply a 20"x70 inch piece of thin plywood with all my extra sheets on top of it, then on top of that 1" foam, on top of that a 23"x75" self-inflating sleeping mat with sheets, and down comforter
I ran pvc pipe so I have a sort of horizontal spine running through my car from back right passenger handle to back left passenger handle
Air circulation is a must during summer. Cracking the trunk during the day and having two fans blowing in the car works wonders
Block out your windows with diy homemade shades/curtains, or buy custom cut shades specific for your vehicle
I poo in my bag, and throw it away right after. I had a nice collapsable toilet with toilet seat but I prefer my thing I got from the home improvement store; it's for routing pipe I believe. It takes up a smaller footprint. My pee container lasts me about half a day before needing to empty it
Wiping down with a wet towel & soap every night keeps me clean, although when I prefer to have a "real shower" I shower discreetly in the back of grocery store parking lots, industrial areas, or at parks. I heat up my 5 gallon when needed with my 1500w immersion water heater when I can find an open outlet. When I do not feel like being discreet I go to a park, set up my pop up changing tent, and have a steamy shower inside. When I feel like being free I go to BLM land and shower outside in Nature
As an audiophile living in my car, I highly recommend this bluetooth speaker. I bought two so I can pair them in stereo and it's so worth it
This rechargeable small guitar amp thing with effects keeps me entertained
A 12v laptop charger is way more efficient than a 110v standard plug
Keep your mind busy
I used to live in a RAV-4; a Crosstrek is a similar SUV. Currently I am living in my 4-door car. I took out the back seats which is a tiny bit of work (just a couple of screws, look up your exact car's rear seat removal on Youtube it's easy) and threw in a bed on a piece of plywood. I will comment below with additional helpful information
Buy a portable power bank if you can't afford an auxillary (additional) battery. I use a $150 250wh power station and am happy with it. For solar, when needed, I use this $190 120w foldable solar panel For a long term solution, should you ever decide to do so, get a $690 100ah LiFePo battery and you should be pleased. I keep this charged with my vehicle using a $115 DC-DC battery charger. For charging smaller items a solar panel is sufficient if you're looking to save money
This is my favorite fan
