Low Rider.....
 

I have a 94 6.5 turbo c-3500 long cab long bed dually, thats a low rider. I only had it a couple weeks now, but I'm thinking its gonna need a full bag set up. It has small helper bags in rear already. My question is... do I go with bags on the leaf springs in the rear again, or do I go with true bag set up back there? What brand should I be looking at as well?

i would say that if your good at fab then build your own bag set-up. there was a a dually like yours that was featured in trucking twice with two different builds with the same truck some years back that had some sick bag set-ups and supposedly still pulled a gooseneck with it
