I see by the owner's manual that the total towing capacity for my 5.9 24 valve Dodge 3500 4x2 is about 13000 and the rig I am looking at is 14000
Any ideas?

I have a 2001 Dodge 3500 diesel dually. I pull a 5th wheel triple axle toyhauler that weighs a touch over 15,000 lbs. The engine has been fiddled with, and the NV5600 has a new clutch, but the truck pulls very well. I have to keep an eye on the pyrometer because it's very easy to get too enthusiastic with the go pedal and the temps can get very high with injudicious use of the right foot.

I pulled a 35' 5th wheel before this one and it weighed about 12,500 lbs. The truck pulled that thing with no issue at all, and got around 11.5 mpg. And that was with a basically stock engine.
