Considering adding air bags to my truck

I have the Firestone airbags in the Chevy dually. Not to level the ride but to smooth it out. A dually rides like a tank, especially when empty. The airbags take the spring recoil out of the ride. It was a huge improvement to the trucks ride quality, with or without the trailer. Without the trailer, I keep the bags at 20-25 psi. With the 5ver, between 30-40 psi. You should never go below 10 psi per the Firestone documentation.
