My hitch was the reese dual cam so I can't tell you how to adjust washers on the equalizer As I'm not as familiar with that hitch. I just know the desired results. Even playing with the hitching change your overweight issue but it might help porpoising issue.

It looks to me like your weights all look pretty normal except you are 180 over your GVWR. I wouldn't worry about that. The one thing I see is that you are only returning 67% of the weight that comes off the front, back with WD. That isn't terrible, but is likely the source of your porpoising. I'd adjust your hitch to return more of the weight. Ideally you want to return 100%, but not more. Depending on your hitch brand, you could tighten up the chains another link, or give the hitch head a little more tilt via spacers or whatever mechanism it uses.

I ended up adding a washer to the hitch so now I have a total of 7 washers. Will see what changes this makes

I hadn't realized that you were working with an Equalizer. Adding another washer is the correct solution. I think you will notice the difference, both in the amount of porpoising you experience, and in the general handling of the whole rig.

One more thing to check. With the rig parked in a level spot, if you measure from the trailer frame to the ground both front and back, the trailer should be level to slightly down in front. If the front is above level, you could lower the hitch head one bolt hole. Doing so will be equivalent to adding a washer to the head angle.

Good luck

Here are my numbers.
Top is just my truck with myself, my son and demco hijacker hitch.

Middle is 377v attached. About 300lbs of cargo in it and total of 6 people in my truck.

Bottom is about 800lbs of "stuff", golf cart and 6 people in my truck.

I did the math but can't find the paper I wrote them on sorry.
