equal-i-zer can't hitch with more spacer washers

I've towed successfully with the 10k equal-i-zer and my nissan titan. I had it setup perfectly. Then I got a new truck, Ram 2500, and a trailer that sits higher. Now I find it extremely difficult to hitch and unhitch. The more spacer washers I use the more difficult or impossible it is. I currently am using only a single washer and it's still challenging to get the coupler engaged and even more difficult to get it off. I've moved the L bar brackets as far up as I can. The arms are not even remotely parallel to the frame now but it's the only way I can get enough weight distribution without the use of more washers.
I am using the equal-i-zer grease on the hitch ball.

Is there any way to use more washers and make it easier to couple/decouple?
