Just had them hauled home yesterday. Two '48 chevy dump trucks. They both have steel dump bodies, one is 8'X 9', the other is 7' X 8'. The name plate on the side of the hood says "Loadmaster". How do I tell if they're 1,1-1/2 or 2 ton? Also how do I find out what size engines are in them, 216 or 235?
