Progressive AAL .... and bags? Another AAL? Leaf swap?

Hello! I just added some new to me
Kings upfront, OME sport shocks in the rear and a new 1.5” all pro AAL on some lightly used TSB springs, with overload.

truck sits great in the driveway and about half loaded...but once the drawers are full, coolers in the back and camping gear, I got some heavy bro lean and only like 1.5 or 2” of down travel before hitting the bump stops in the rear.

Is this a classic example of “do it right the first time”? And am I about to order a new leaf pack with timbrens on Sunday night? My guess is yes, but figured I’d check here first.

can I add another leaf into this thing to give it a bit more support? With the progressive leaf? Or should I run airbags as the truck isn’t fully loaded very often. I don’t know squat about airbags but worry about them making any work on the rear nil off road.

here’s a picture of how she sits at home with drawers, topper, awning, and two bike racks.
