With the trailer sitting on the tongue without a wd hitch and with a 5" raise lift from napa, I have several inches of spring left before it hits the rubber snubber and truck rides perfectly straight without squatting and the trailer is straight as well. If I want to add some weight to the truck Theres an air bag kit I can add inside the springs for less than 100 bucks that will raise the payload capacity greatly If I want. I would feel safe towing as much as 9k with it personally.
Are you sure those airbags will increase the payload? Payload isn't a function of how much weight your springs and axles will hold. It takes into account many factors such as transmission strength, engine, brakes, etc. If you add airbags there is still just as much weight acting on those parts. There are max pin weights listed on a sticker on your truck. That is what each axle will hold, yet it's often more than the payload capacity.
No trying to prove you are incorrect, just pointing out that you may really want to research that claim before dropping cash on airbags. My understanding is they really just help it ride level and smoother if needed
