Air bags will make the truck handle better. Increase air pressure in the tires to make the truck more stable. Your payload capacity is etched in stone on the door sticker. IMO a 5-5500 lb dry trailer is a better match for a Ram 1500.
My TT is 6331lb dry. I have estimated my tongue weight around 1100lb give or take 50. My truck has 1255CCC so you can see what I mean by someone getting in the truck(that's me).
It is your personal decision. Are you used to towing and know what to expect from this weight level? It will only come into play in two situations; You have an accident and get sued ( they have to prove you are over) or you have a warranty issue with the truck due to overloading.
Just about everything I see around here (this part of the world) is overloaded if it make you feel any better
