Equalizer Question

I just went out and adjusted my Equalizer one more time. But this time, I'm really, really close. The trailer dropped a 1/4" in the front and the truck only raised a 1/4" in the front.

To make the bars as close to parallel to the trailer, I had to drop the L brackets. No problem. But now finally to my question.

In order to get these measurements with the L brackets dropped, I had to use eight washers on the spacer rivet. I have no instructions as my dealer set up the hitch and didn't leave the instructions with us. Is there a maximum of washers you can use on the spacer rivet? The rivet still has over 1/4" of shaft into the hitch head. But with the camper down a 1/4" in the front (the quad and everything is loaded up in the back), I'd like to bring that up some more; especially knowing that without the quad in the back, it'll be slightly heavier on the tongue.

If you want to do it correctly go to the scales and weigh the front axle of your truck with and without the trailer tongue/trailer. Then determine if you need to add back half or full weight taken off the front axle by the tongue. Some manufacturers specify only adding back half that taken off by the trailer. Get to that number by adjusting the washers and L brackets to fit the new weight parameters.
