I'm looking at a 99 dually with a 6.5 diesel 4x4.
It has 126,100 miles on it.

This will be used to tow maybe 20% of the time.
The trailer I'll be towing will weigh around 10,500

Anyone have any experiences with this truck, good or bad?

Anyone know the towing limit for this truck as well?

Any information you can give would be greatly appreciated
