That old freightshaker. Spine hurts looking at it.
However thats either a brockway or a autocar possibly next picture down. I had a old 84 autocar for a while once. Loved on that thing. Boss man was thinking I had gone nuts taking care of it. there has been only two trucks worthy of that love. A old 75 daycab freight shaker with the 13 on a 425 cat and that autocar. It did have one failing. A wee bit stiff on that suspension at times.
I can imagine some of our esteemed 21's would whine if faced with that Autocar. I would not be afraid to take it to Donner in winter.
