Have felt since the '70s that the first one is where you make all the mistakes, then when you know where all the traps are when you build the second.

These reviews are exceptionally helpful to identify any 'traps' - makes the whole build that much better.

Some of the YT content helps, here. But the only hangup with that is that I can read 10X faster than I can watch.

Friend of mine across the street in Deerburn used to have one, used it for towing his boat (and he lived at home, LOL.) Rode in it several times when I worked for his painting company in the 80-something.
