The rear and isn’t a Dana 80 it’s a Dana 70. Only the diesel powered, manual trans 2500 had a Dana 80.
The 70 has about a 7500 pound rating from Dana if I recall correctly. Just make sure you put on rear tires with enough load rating, and don’t believe any advertised camper weights, especially “dry weight”. You have to drive it on a scale. It’ll be more than anyone tells you.
However, it’s absolutely capable of hauling a pretty large camper.
Before ‘03, Dodge didn’t play the silly single rear wheel one-ton badging game (and sell you the same truck as a 2500).
They just built the 2500 with stout springs.
I always think it’s funny when people say you cannot increase a truck’s payload by installing bigger springs, yet they believe if the factory bolts the same ones in, it does!
