Did you get the "extra" leaf with them? I have a TRD Pro Taco w/ a SnugTop and whenever I actually load it up for camping the rear sags badly. Haven't dealt with it yet but you've got me thinking...it's my daily though so don't want anything too rough...it's a camping rig whereas the LX is for wheeling.Upgraded to the heavy dakar springs. Wasn't a fun installation by myself. My old pack was totally flat due to constant weight of camper shell, plus an extra 200-300lbs of gear while working. So far seem nice, surprisingly compliant.
