Thanks guys. I cannot remember the tongue weight, but I do have it written down at home. I'll let you know later. I have not done anything with the suspension. It is the stock 3.55. I have not had any issues at all. The trailer is 4,000 pounds.
Nice combo! but the trailer looks a bit high in the front( might be the angle of the photo?). Too little tongue weight could give you trailer sway issues..
