NEVER use either or starting fluid in a 6.2 diesel or any diesel for that matter , especially a well used one . NFN , but that is one rough looking truck , what it's worth is what YOU are willing to pay for it . I also agree , do not DRIVE that back to Rochester , but that's just me , I do NOT like sitting on the side of the road waiting for a TOW . Pull the shafts and dolly it or trailer it save yourself some early grief . REMEMBER you have to pick your battles . BTW , welcome aboard and good luck
