Mine was 5320 lbs on the front and 4900 lbs on the rear with just my deck,two lower boxes, goose neck and SuperHitch without anyone in the truck. This is a Tradesman trim without the mid tank, so pretty close numbers if you consider all your extras in the cab.
Check your GVWR. The last time I looked, the 60" CA had a slightly lower 19,000 lb rating and the 84" CA got the 19,500 lb ratings.
The rear 111S axle is rated by Dana at 14,500 lbs although Ram derates it to 13,500 lbs. I have not found any other ratings or applications for the front Magna Steyr axle other than Ram's 7250 lb.
