I might be out of line to suggest this, but you could trade your car for a pickup with a campershell that has screened windows on both sides. I love pickup trucks with shells. They have plenty of room for sleeping, storage, and if its a 4X4, then its better at bugging out on questionable roads. I especially like the ones with the window behind the benchseat that you can crawl through to get from the cabin to the bed and vise versa.
The only advantage I can think of that a car has over a pickup is that it can carry more seat-belted passengers.
I will never buy a mere car.
Pickups and dual-purpose motorcycles only. Maybe a van. No, vans are for psychedelic partyers in their early twenties. Been there, done that.
