@heybaylor..quote interesting analogy. Never thought about that. What do you mean "if tongue weight too low"? @trlrman..the aire pressure is at 55psi per specs. Thank you all for the help.
I copied this from the GMC website, I used to tow with a full size Bronco.(short wheelbase)
moving the boat on the trailer to adjust tonque weight was critical ( 1 inch made a difference)
"How Tongue Weight Affects Your Vehicle"
"The tongue weight is the static force the trailer tongue exerts on the hitch ball. Proper trailer tongue weight can make the difference between a safe trailer towing experience and a dangerous journey. If you don’t have enough weight on the trailer tongue, the trailer may be prone to swaying from side to side, making it difficult to control. Conversely, if you have too much weight exerted on the hitch ball, the force could overload the rear tires of the tow vehicle and push the rear end of the vehicle around. This could also negatively affect handling – you might not be able to go around corners and curves properly, and your vehicle may not stop quickly enough when you press the brake pedal."
