Maybe you can verify information I got from a retired vehicle engineer that now teaching engineering at the college level. He said there are test done with plate between the 5er hitch that can measure weight changes while towing. He stated the scale weight is a static weight and that while towing the pin weight can vary by 30% or more. Hitting the dip in road or going down steep hill and applying the brakes shifts weight forward onto the pin. Is this true? So that 3,000 lbs pin weight can jump up to 3900 lbs or more. That is why you should leave a margin between max axle/tire ratings and stay close to the CC of the TV.
