As Bozo said, research your truck numbers. Compare those to your trailer numbers. Be sure to include any upgrades that you might have speced.
It is only my opinion, but on the surface, And without knowing specifics of the proposed set up, I would think that you would be over weight trying to use a Ram 1500.
Remember you need some Safety Margin as well.
Remember everything and I mean everything, you place in or on the truck reduces the payload available and impacts the numbers below.
Important check points:
GVW
GVWR
GCVWR
Payload
Front Axle Weight Rating
Rear Axle Weight Rating
Tire Weight Rating
Trailer GVWR
Trailer Payload Capacity
Tongue Weight/Hitch weight
We have friends using an F250 to pull a Delta RK. I don’t know their specific numbers.
I suggest a pause, deep breath, and a lot of research. Don’t take a salesperson’s word , make them prove out the numbers on the unit that you are trying to buy.
Best regards
