One thing that everyone seems to forget are the brakes. With the '11-13 V6 Durango when you ordered the factory tow package you got the HD V8 brakes. With the '14+ Durango V6 the HD V8 brakes were no longer part of the factory tow package. But the HD V8 brakes are standard on the '14+ Citadel whether you have the factory tow package or not. Yes I know that all sound crazy. So if you plan to tow a heavy trailer with a '14+ V6 Durango, I would recommend that you either start with a Citadel that has the factory tow package, upgrade the front and rear brakes on your '14+ V6 Durango non-Citadel model that has the factory tow package (which is what I did to mine) or simple just buy the V8 Durango with a tow package.
