Could someone give me a rough number on how many 60/61 c-30 or greater trucks were made? did the 1T+ trucks have a 4X4 option? What was the highest weight ration before the truck went to the bigger commercial body style? Last of all, is there a way to make heavy trucks get better gas milage? I was having another thought today on the 61' wrecker I wanted to create, and I wanted to know some stuff about the production of heavier apache's. What is the suggested rating for a wrecker other than a regular C-30?
