Payload is 500 lbs over wait I also have a 60 gallons transfer diesel tool box
Boy are you asking for trouble. A 2500 is not enough truck for that kind of load, and if you do haul it and break something warranty is void.
Diesel fuel weighs in the area of 7 lbs per gallon so now you are over weight by at least 1,000 lbs. Not good!
