10% TW to 13% TW...did not seem to make any difference

Here is how I meaure tongue weight.

Using a Sherline tongue weight scale under the tongue jack, I adjust the trailer to the towing stance (which in may case is just slightly nose down) and take the reading.

I understand that, given the attach point to the vehicle is about 18 inches in front of the Tongue Jack, this TW measurement is not exact, but it should be rather close..
