My 2013 has a GCWR of 25,000#and a tow capacity of 17,700#. No doubt it can pull a 15,000# fiver with a pin weight of around 2,500+-. I have looked at the DRV's and most are up in the 22,000# with a pin around 3,200+. If you look at a 3500/F350, they shouldn't be pulling one of those either. You would need a Freightliner M2 at the least. A friend of mine pulls for Indiana across County with a 2500 with air bags and had 350,000 miles on his last 2500 and over 150,000 on his 2014 2500. He hasn't had any issues going from Indiana to LA and is leaving with a DRV to Seattle. So I guess it's a matter of do I or don't I?
