Air bag question and suspension in general I guess

Had airbags, supersprings, and sway bar on last truck. Won’t do airbags again. There are better options, less hassle, more robust. With the tongue weight you are suggesting, I don’t think airbags are necessary.
FWIW; I question the weight of that TC also.

Visit the scales and then report back here. Guessing at your weights isn’t very helpful.
