Do you plan to do heavy towing or is this just for softer rear suspension or both? Load leveler bags work decently if you towing heavy loads but are not the greatest when the truck is empty. If your looking for a softer ride when empty and to lift the rear back up when loaded I would go with a sleeve style airbag over a double convoluted bag. Maybe even pull a leaf from the leaf pack. A double convoluted airbag has a very progressive spring rate...it gets incrementally stiffer the farther it is compressed. A sleeve style airbag has a much more linear spring rate.
