A lot of excellent ideas in this build. Not cheap - he spent $20,000 on the build. But the video has a link to all the drawings and parts lists. Add labor to that $20,000 and this is a very expensive vehicle. I think it is great he gives the drawings. I am researching all the ways people do stuff, and looked hard at 80/20 but that stuff is expensive. With a set of drawings you could avoid wasting material and money.
For myself I want to just get in the field for a while and see what I need to be comfortable. Let the stuff talk to me, rather than me tell the stuff. I am not that smart I can figure it out, but I am an OK listener.
One day. I will watch this video several times, I am sure. I like the way this guy thinks.
