How to upgrade or modify Tacoma Pro suspension for added weight?

Hi all.
I looked for a bit but could be lacking on my Google Fu.
I have added quite a bit of weight by now to my '19 Pro. The latest impact is a Alu Cab 3.0 with the shadow awning and now feel I'm riding in different truck altogether.
Besides the Alu Cab:
Uptop Alpha cab rack
Uptop softopper Truss
RCI rock sliders
Softopper (minimal lbs)
And I plan on adding front bumper with winch and finally rear bump (potentially swing etc)

I overland and off-road so loads are somewhat dynamic.

Naturally I have bed filled with camping goodies and additionally may have 1 to 2 kayaks on Alucab
Potentially worth noting I am never shy of a 300lb man with woman and dog
And I plan on towing a 14' boat with trailer TBD

Sounding like I want a bigger truck by now I know lol.

Immediately I'm assuming leaf spring modification is my go to but am wanting to make sure I have my game plan correct!
Any input is much appreciated y'all.

 

You have too much weight for an ad a leaf, you'll need a whole new leaf pack. You probably need some help up front too, but that's harder if you're trying to keep the pro coilovers.

 

My only intent to keep anything is its ability to keep up
If I need to replace the unit as a whole or can stage it out depends on what knowledge I learn.
Thank you

 

Firestone airbags.

 

Add a leaf and Firestone airbags.

 

Your constant load is likely too heavy for an AAL to handle properly. Go for a full leaf pack to handle the constant load, and add air bags if/when you start towing as well. The Archive or BAMF shackle hangers provide increased stability in the rear end while carrying a heavy load, especially if you employ the optional cross bar.
