I'm sure he has worked his way up to this lift. Still, more than a half ton without external supports is rather mind blowing. If you think about how small the verteberal facet joints are, and the disc space loading; I just cringe watching the lift and hold.
I do congratulate him to have spent all the time and effort to lift such a load. If you have a flat tire, and no car jack, this guy could be a huge help.
