Towing Capacity 2016 Chevy

Anyone know right off hand the 5th wheel towing capacity for the 2016 2500 D/A, general speaking. I know there can be variables that effect it, such as tire size, etc. Was talking to a salesman recently who said he thought it was around 13,900, which struck me as being low. I know you can look at the Chevy website, but that can be misleading unless you know specifics. I'm hoping someone who actually has one can chime in.
