If you're an expert in tractor trailer trucks, please answer this question. I want to reconstruct the Mack Super-liner from Mighty Machines At the Demolition Site for MMD, but what is that tank cylinder mounted on the back just behind the cab just over the drop axle? It isn't a reefer tank or a propane tank, but it's there for a reason.
