TRDOR rear bottoming, how to cure and retain plush ride?

My 3rd gen 2017 TRDOR with stock OR suspension bottoms the rear in a bunch of locations on my ride home. Granted, this road is partially paved with lots of steep ups and downs, and I drive it energetically when the touristas are absent. Sometimes I run empty, sometimes pretty well loaded.

Road surface is rough, big potholes in the paved parts, lava rocks and holes in and streams in the unpaved sections. I like a plush but controllable ride, so don't want to go too firm. Running KO2's on stock rims in 265/75R16 in E range for the lava rocks and nails, not looking for more lift clearance.

Anyone got any suggestions? I don't remember my 2nd gen 2012 TRDOR bottoming out in the rear.

 

Are your leafs flat?

 

Ride rite air bags. Unlike add-a-leafs they allow you to retain stock ride when empty or loaded since you can vary the pressure. Can be set up to adjust on the fly using available kits or DIY.

 

Never occurred to me. Only 5k miles and never heavily overloaded. I have a service coming up, I'll get that checked. It does seem to bottom out much too easily.

 

I would always bottom out hitting the bump stops with my stock leafs before I did an AAL
