I actually did some google mining on that question before my posted reply and cannot find anything that states less than 20%. I did find some references to toy haulers that, without "toys" in the garage were running up to 34% and pulled like they were "on rails".
I suspect that, for local hauls, having a light pin weight may work... but for highway stability less than 20% might get dicey. It would be nice to see a standard somewhere, even if it isn't an "ANSI" or "SAE" type of thing. I know 5th wheels are commonly stated as close to 25% and gooseneck's at 20%, but have never seen a standard.
Certainly if Ram/Ford/GM is going to say a truck will tow a 35,100 or 35,500 pound gooseneck they are basing that on something other than a by gosh and by golly pin weight estimate...
It would have been nice had they stated the CAT weights.
