Welcome to stovebolt...
Nice looking C60, looks like the one I saw on ebay for $1000 in North Carolina a couple of weeks ago. If so you got a good buy in my opinion. As far as the 19,000 GVW it should be correct with your truck specs. My '57 Chev. 6400 (same as a C60) has a GVW of 19,500 lbs and it has similar components, except it has 10X22.5 tubeless tires. Yours is fine for carrying 5 to 6 tons safely as long as your brakes are right. Don't plan on a lot of speed as these trucks were originally meant to run at speeds of 45 to 50 MPH. I've had great service with mine.
Look forward to hearing more about your truck!
