ram load leveling suspension question?

Thanks for the responses so far,one of the reasons we are strongley considering the ram is the cummins engine where me and my wife work we use them in commercial busses a n d yes i know it is not the same engine,as what is in the ram I am familiar with how tough they are and the injection pump failure on the cp4 is well documented and it is another reason,which i am leary to go with the ford or gm, and we have bought gm products many times.and yes I agree ford does build a good truck. I will check out ram owners forum,the reason we are shying away from drw is mainly the cost of maintaining it , ( brakes ,tires ) and the stigma that 1 tons are commercial vehicles, and we live in a hoa,although it is better then some .thanks so far I think we may pass on the air suspension, but we will also do some more homework .
