After around 4 hours of wipes, I ended up soloing this bad boy. Ever since the two man video came out I wanted to burn some time to solo it, and I ended up going for it this Tuesday. It was a pretty good kill despite the bad luck in the end, (I evacuated the demolisher and ended up on the wrong side) and I'm sure its repeatable. He dropped about 200g and some BoE bracers, making my time spent not completely wasted.
I saw a video of a solo kill from 2 weeks ago after doing it myself. The video involved flame leviathan chasing empty vehicles non stop, so I don't really know what to make of it.
