Searching for specific stealth Van Tour on YouTube

Hey Guys,

a few months ago i saw an interesting Van Build but i can´t find the video anymore.
If i remember correctly it was a box Truck that was very stealthy. The bedroom was like a cave that you can climb into and it was also soundproof.

I know that´s not much, but hopefully someone knows where i can find that build. It´s my dream build but i accidentaly didn´t like the video.
