They have been increasing these trucks over the years to handle a lot of these larger fifth wheels. When shopping pay attention to your specs and you will have no issues.
For that high of towing your RV will need to be a triple axle with no more than 15% pin.
Tow it, sure but can it HANDLE it???
Do you really think the Manufacture will post weights on the inside of the door if the truck could not handle it?
Stay under parameters of your truck and it will handle it.
