Sorry to hear this Danny.
It seems to me that ultra high mileage vehicles do best when their owners put the sweat equity into them like you did and keep them for their personal use for a long time.
The sweat equity and quality seems to be lost on most strangers when confronted with the high mileage.
Even with the mavens among us, no takers
I hope you have success in selling it as opposed to parting it out.
