96 chevy s10 extcab 4.3 v6

it's my wifes truck, seems she has decided to pull a 2720sl with it. we managed to get a class c hitch, tranny cooler and brake controller put on before we picked up the TM. TM makes the truck squat down bout 6" in the rear. so i'm figuring airbags, airshocks an a wdh would be a good idea. not sure when she planning on getting a bigger truck. i could use some feed back on this idea.
