What in the rear?

What do you think?
I bought a used 2019 TRD Sport and immediately added 1 inch spacers in front, and 1 inch blocks in back with stock shocks and leafs. I want to do new 5100s front and back with probably OME 887 coils in front. But my leafs look flat, (maybe first owner hauled heavy loads regularly?) so I’m questioning whether these saggy leafs are worth adding 3 leaf progressives to, or whether to skip that and just go with new leaf packs? If so which replacement leafs would pair well with the 887s? It’s my daily driver, usually the bed is empty. But a half dozen times per year I load some firewood, camping gear, etc. and tow my 3000 lb camper to a state park. So aal or new leafs? Thanks for any input.

 

Here’s what I used.
