One of the towing companies here in the Tampa Bay Fl area we have one company who has a truck with Miller's truck body for towing. That company is Stepps Towing. He has the Rotator like Ron Pratt does.
I mean if you're going to spend the 3 quarters of a million dollars on a truck i'm sure they would give you a metric chart if you requested, But it is an American company and the trucks are made in America and used in America so by default it's not going to be metric.
stick with the mmo lol too many levers and probably more mechanical parts, but you know what would be sick if the tunnel box was made into a little bedroom
