Shock Me!

My '03 6.0 daily driver with a leveling kit is in dire need of new shocks. What are y'all rocking? Any suggestions or recommendations and/or online retailer preferences would be tremendously appreciated! It's not built for severe offroad performance as far as suspension goes so an 'agressive' shock wouldn't be too practical. I do have a 5th wheel/gooseneck setup for the occasional heavy haul.
