static drop ?'s and pics..diff between 3/4&5/7

Looking specifically for pics from you guys with(or have had in past w/pics)3/4 or 5/7 static drops, got a 35ft gooseneck camper i pull with this truck(probably weighs in at 9-12k) ...I know i have been told to use helper bags over the axle, but would they be necessary with the 3/4 drop? Don't want anything to drastic just get it a little closer to the ground and still be functional.
