Hi Bee,
You for sure have a great truck for towing the camper no problem there.
Now to the hitch, see this post where I weighed 2 loaded T2363's the way folks go camping.
Sunline Camper Actual Loaded Tongue/Pin Weights
Be expecting a 650 to possibly 700# loaded tongue weight. Yes, stuff adds up....LOL It is amazing what "stuff" weighs. And most is all in 10 or 20# items, just a lot of them.
And then there is gear in the bed of the truck. Weight behind the rear axle works on the WD hitch. Best is to move heavy items to behind the cab verses right on the tail gate are. This helps reduce the effect on the WD hitch.
With a 650 to 700# loaded tongue weight it is almost a mandate to use a WD hitch just for the truck receiver. Look at your reciever, there should be 2 ratings on it.
Weight carrying, this is raw tongue weight. It is often at 500# even on a 2500.
Weight Distributing, this is the tongue weight the receiver can use handle with a WD hitch. This number is usually always higher then the weight carrying number.
See this sticker off my F350 as Ford gives as stock.
Odds are high your Dodge is close to the same unless you upgraded it.
Even if you have an upgraded receiver, having a 650 to 700# tongue weight hanging some 65 " behind the rear axle can benefit in truck steering from using a WD hitch. The truck will be more solid in the front end. Now I know you have that monster CTD up front, but it still can help.
For that size TT, an 800 for 750# WD hitch would be a good size. And they make several with built in sway control.
Equal-L-izer brand by Progress Mfg makes one, they offer a 600# unit in their 4 point then jump to a 1,000# system.

Reese makes one that is a combo unit too, called their SC hitch. This one you can upgrade the WD bars if some day you buy a bigger camper. The Equal-I-zer you have to buy the whole new hitch.

You may need a longer drop shank and a tow ball top go with either of those hitches.
And then there is the standard WD hitch with a friction add on sway bar. In your case this will work too with the heavy truck.
Hope this helps and let us know if you need more.
