You might want to reread your thread. Towing is relevant when it comes to suspension and it took several posts for you to say you tow and, I believe you still don’t post a picture of your truck with the trailer attached. Regardless, you have your solutions and you’re a better tower for the information you were given. I’d replace your springs sooner than later though. The Deavers are a good solution for you along with a drop hitch and a cargo readjustment.
Regarding the op, the first post seems like a troll. Reread it and you will see he didn’t ask for help. Just complained. I didn’t tear him to shreds until later. Read up to post 12 and you’ll see what I mean.
