My 2 cents onthe subject, Most folks put way too much on the back of their trucks so much so as they are over what the manufacture recommends. I will be told that I an full of crap and that "I do it all the time with no issue", but that is not the case.
The factory suspension is setup to handle a specific amount of weight to provide a car like ride that most require or have come to know. The issue comes when the truck is loaded to 80-100%+ of that rated capacity. Air bags helper springs, more springs, Air Suspensions are all directions to go in and there for the most part is little thought given to the system as a whole.
If you are happy with the ride quality of your rig hauling the fiver why would you change it. If your not examin the whole system and see what can be improved. Spring rates, Tire size/width, axle capacity, brake capacity, gearing, etc.
In my case, I wanted a better quality of ride light loaded but retain the load carring capacity loaded plus the added benifit of automatic load leveling.
My rig is set up to haul a slide on camper at 5500#dry. add another 1500# wet and loaded there is a bunch of weight up there.
The lowest capacity is the Air suspension at 13,000#, followed by the rear Axle (S14 110L) at 14,000# and the tires at 23,200# @110PSI. My truck weighs in at 9900# with a 60/40 split empty I have 4000# on the rear end subtract that fromthe lowest capacity system (Air Springs) I have a true #9000 carying capacity and a 2000# safety margin.
Look at your weights and capacities and do the math, you will quickly find out where things stack up and what needs to be improved/replaced.
I suspect just using your picture as a reference you rig rides fine with the said load hooked up.
Again just my 2 cents.
