"Tiny homes on wheels" embody the spirit of vanlife. Chances are you've walked by such a van without even knowing it. Solar panels and a fan on the roof may be the only sign that a small, off-grid house is inside.
I started converting a Ford Transit 250 into a tiny home back in late 2017. Since then, I've put tens of thousands of miles on my little mobile cabin. Inside, it's complete with a sink, stove, refrigerator, workstation, and plenty of space for clothes and supplies. Even at 6'2" tall, I can stand up inside and move around comfortably.
Building the van has been both educational and satisfying. I've learned about every aisle in the hardware store, and been able to visit even the remote corners of national parks. No RV-style "hookups" are required, because the van is solar powered and self-contained.
