Airbag HELP Is there such a thing as perfect bag setup

Ok, so all I want is airbags. I just want everything to function propperly and not have to worry about everything everytime i drive somewhere. I have a cavalier and had a cheap kit once before. I then sold that b/c of all the problems. now i got a 2500 easystreet kit. the back bags rub the rear wheels, the pressure switch isnt working, it has slow leaks.. ETC. All i want is a bag setup i can drive and not worry about. I'm only 21 and already have sopme grey hairs and dont really care to get more over airbag suspension. I'm very frustrated right now
any help or suggestions to motivate me not to sell the bags AGAIN
