Kind of leaning towards just skipping the lower stableloads and just using the Firestone airbags in conjunction with the existing upper stableloads that are one there. I was thinking about it last night and I gather the point of these is to preload the overloads because in many instances they won't even engage with a load in the bed, but I am just about at my max payload hovering around 4500-5000 lbs. in the truck bed. Shouldn't that be enough weight to sufficiently engage the overloads? Are the stabeloads even necessary with a weight that large?
Yes, but raising the back with the bags will disengage the lower stock overloads at some point and possibly result in too much sway. You may be able to get as much lift as you want with the bags without disengaging the lower stock overloads without going to lower stableloads if you inflate the bags just below the point where the lowers are disengaged. Maybe you should take an incremental approach and do the airbags first and see how it works out without the lower stableloads.
I did find that the lower stableloads are much more complicated to install than the uppers. It's not difficult, but there are lots of parts and figuring out how it all goes together from the instructions and pictures was a challenge on the first one. After the first one was done, each additional one was easy and only took about 15-minutes. I'm an engineer with moderate wrenching skills.
