I friggin LOVE this thing, I almost wanted to abandon ship on the lunchbox and start building a step van after seeing this picture
If I recall it had originally been set up as some sort of train track maintenance vehicle. It had the mechanism that allowed it to run on the rails, which had been removed. It had some big honkin diesel in it and it sold for some stupid cheap sub $5k price. I came REAL close to pulling the trigger on this thing but thank my various gods good sense prevailed. Like I need another project.
