>>1693717It's made for SUVs, which I reckoned would fit perfectly in Falkor because it's an extended cab which is approx the same dimensions of a 4-door SUV, and I was right. It's 3 larger segments and 2 small ones (to buffer the wheel wells). They're attached but fold onto each other in various configurations, and they all inflate separately which is quite handy. I don't think I'll be inflating the tiny wheel pillows when I take it for a first sleep this weekend, just takes up more space and don't need the buffer. Would fit in OP's jam quite well I would think.
You can find it on Amazon for various prices around AU$100
