I really don't see how that would happen. Every triple axle has a lower pid that I have seen. Sounds like your axles need to be moved back to get you to 20% or more pin. More would be better then it would come down some with the bike on board.

As to the random "at least it's not a Harley" comment. I went from a 1100 V Star Yami to a 09 HD UltraGlide, no comparison in so many ways.

Moving the axles back does the same thing as adding a third axle behind the tandems. Both place the center of the axles further back from the center of the load.

I really don't like to challenge any on your comments as I know you are an intelligent guy and usually agree with your comments BUT I don't see how adding an axle BEHIND your existing axles will change enough to make it worth while. I am not an engineer but the front axle placement has more to do with more or less pin weight. Moving your axles back will do much more.

Think about it this way: the trailer is a big teeter totter. The fulcrum of the teeter totter is not quite as precise when multiple axles are used and you're focussing on the weight being carried by the truck and seeing the fulcrum as being the front axle. If you look at the teeter totter in the same way but from the rear axle back and consider how much weight the bike is lifting off the truck you would see the fulcrum point as the rear axle. Consider if you added axles all the way to the back of the trailer. The bike wouldn't have any lifting effect on the pin.
