I found them yesterday after some fighting around the sliders....if those aren't on the truck, they're clear as can be. Will try to get a couple of pics and post them for reference. It's a slight opening in the pinch weld front and rear on the rocker panels each side - easily missed if they're...
Funny...just digging into this myself. There's a few threads referencing the plugged holes on the bottom of the rockers, but there are also a couple of small slit drains along the pinch weld. Sounds simple, but I'm still hunting for them (and a bit obstructed by the WKOR sliders).
No good pics...
