Your only real concerns will be your trucks payload and the trailers pin weight. Some Rams have pretty low payloads, under 1100lbs. Check your door jamb sticker for yours. From that number you need to subtract the weight of passengers and anything you plan to carry in the truck, plus the weight of the 5th wheel hitch. What is left is what you can afford for the trailers pin weight. Most fivers have 20-25% of their loaded weight carried on the pin.
If you have the payload available to carry all that then you should be good to go.
