52 Ton -- Keep after it, Brother! Maybe it will help if you don't look at it as a whole truck that is now in pieces but rather as a series of little, manageable projects that you can knock out as you have time and inclination. Enjoy the tasks and each little victory.
You have friends and brothers/sisters here. A lot of us have been where you are (medically and projectwise). We're here to help or commiserate ... whatever you need.
