Thanks for the pictures. This looks very promising, as the rear suspension seems to be barely sagging if at all with this large (but empty) trailer. Our 4 door wrangler sinks more in the rear with just a jet ski in tow, and sinks almost down to the bottom with a 3500 lb enclosed work trailer (I only tow that at low speeds around refineries), and that wrangler is rated the same as the bronco at 3500 lbs. I don’t want to speak too soon, but this helps solidify my suspicion that a 4 door bronco can be capable of safely towing more than 3500 lbs if necessary.
