You will rarely find a 5th Wheel Camping type trailer that puts down less than 20% of the trailer weight on the hitch, via the pin. 21%, 22%, and 23% are a lot more common numbers, and once in a while you will see some that may go up to 25%. So if Chevy/GM is saying 15%, they simply do not have a clue on reality. Imagine that, someone in Corp. that doesn't know their butt from a hole in the ground!
