2+1 Leafs - AAL or New Pack?

I have the 2+1 leaf pack on a ‘13 prerunner with 95k miles. I already did the ‘17 front coilovers and got the 1” lift up front with those. Now, the back is squatting. Is it good to get an aal for this leaf pack or a new leaf pack altogether? I already have an ‘18 3+1 pack uninstalled but looking for the best and easiest to install option under $150.
This is my DD work truck carrying tools and buckets of chemicals sometimes. I also put my motorcycle in the bed sometimes and carry a kayak on a bed rack. Eventually, I might get a rtt on the bed rack. Not looking to rock crawl but some easy trails to get to the campsite are on my radar.

 

The '18 leaf pack is pretty much your current pack with an aal. Install the newer set to level the truck out then add an aal if needed for payload. This would be the cheapest route.
