Ok well the reason why I wasnt thinking body swap is cause my donor truck is extended cab so I dont know if body swap is even possible. So it seems the only option is SAS but I doubt Ill do that so my new plan is put the step side on air and just reuse the lowering kit on the longbed....Ill have two lowered truck one on air and the other static but its all good cause I just picked up a 2 door tahoe for my winter/4x4 needs
well at least you got it all figured out, and another truck in the mix too as a plus
