In order to tow a 5th wheel of any size you need to have ordered your truck with the HD Payload option (8200 lb. payload). YOu can still tow a 5th wheel but it will just need to be a smaller one than otherwise would be possible. Payload is the main thing to look at for 5th wheel towing regardless of WHAT size truck you are using. People are quick to point this out with half ton trucks but it is just as much a factor with 3/4 ton trucks but many just ignore it in that case.
Good luck / Skip
I find myself commonly agreeing with Skip. 1/2 tons just don't have the payload needed to tow much *if* you're going to adhere to all ratings.
The fact that you wanted rear axle weights already says that you're willing to overload the GVWR and limit yourself to rear axle + tire load capacity. A lot of people do it. Not my way, though.
