There's a lot of missing information there. Primarily the length and loaded weight of your trailer, and the specific model/package your truck has that will dictate its towing capacity. Once we have all that math worked out, then airbags could be a supplemental item that will smooth out the towing process. But they will NOT increase your truck's payload (i.e. the cargo it can carry, including the downward-pushing tongue weight) nor the amount of weight your truck can tow.
Two specific numbers I would like to see:
Yellow banner placard on the TRUCK driver door latch post which states ..maximum weight of passengers and cargo shall not exceed XXXX.
GVWR from the CAMPER, usually found on the outside left front corner or inside a kitchen cabinet door.
This will really help us give good advise instead of guessing.
