I don't know anything about the Equalizer WDS, but I will speak to the weight distribution itself.
Weight #1 has a weight distribution ratio of 42% (front) : 58% (rear), which I believe is too little. For my setup I strive for 47% : 53%. That gives me 4,140 lbs on the front and 4600 lbs on the rear. The amount of "lift" on my front axle (as measured from ground to top of wheel well remains the same (39.5") both with and without trailer w/WDS attached.
1. It's not clear to me what your before and after wheel well measurements are. Can you provide them?
2. Is your trailer frame level? I know you said it was, but double check, as this is critical. Measure it at multiple points along the length using a bubble level.. YOU MUST DO THIS FIRST.
3. Once level, measure the distance from the ground to the top of the ball well on the trailer.
4. Next, adjust the height of the ball on the tow vehicle to equal that from Step 3 above ADDING 1/16" for each 100 lbs of tongue weight. So if your tongue weight is 1200 lbs, you would add 12/16 (3/4") of additional height to your ball.
5. Adjust your hitch so that the bars are level with the ground with the WDS engaged. Add/remove washers as required.
6. Re-confirm that your trailer frame is still level.
There's a couple of other things we can do but for now let's try these things. Get those wheel well before/after measurements.
