My 2010 F250 sits about 2" lower than unloaded in the rear with our 900~lb tongue weight. About 3" lower without the WD bars attached. Perfect in my humble opinion. If you need something to bother you, think about the stress the WD bars put on the trailer's A frame. It's already carrying the load of the tongue weight. Then we pull down on the A frame with tremendous force with the bars adding greatly to the stress on the A frame to chassis point. Maybe more than doubling the load. I don't know the calculation or how to measure it. I prefer to use as little WD as is necessary to bring the front of the TV about halfway down to it's unloaded height.
