All hail Hippo man!!
It's still on my watch list to catch up on!
I've done a few 1K day rides over the years. In the US if you stick to interstates and avoid big cities it isn't too bad. Having a touring bike helps a ton too, like a Goldwing or a Road Glide. On a bike like yours with no windshield it can be really rough, it just wears you down.
Honestly I like the idea of making a video about a 1K Iron Butt.
Maybe when PA gets past its lockdown I'll make one too and link your vid to it! Start a little Youtube 1K challenge chain, lol.
