I hate to tell you but if you have 6,500lb trailer and, when hooked up, your rear stays exactly the height it was before then you have a serious problem! Ask anyone in the know, with TT's, approximately 10 - 15% of the weight of your trailer should be on the tongue. Boats are usually less at 7 - 10% on average. So, with a 6,500lb TT you should have a minimum of 650lbs on the tongue and if 650lbs doesn't sag the rear of your Titan some I want to know what airbags your using. I can put my 500lb ATV in the bed of my truck and it drops 1" or so. I think many people misunderstand what the purpose of a weight distributing hitch is. It DOES NOT distribute the ENTIRE tongue weight to the axles of the Tow Vehicle and the trailer, only a portion. Here is my truck and trailer before and after the PRG Leveling Kit. The truck is level in the first photo with the WD hitch setup properly, and sagging in the second photo with the WD hitch setup exactly the same way. Regardless, my rear-end sag is approximately 2.5". Without the WD hitch it sags just over 3". My undistributed (trailer loaded) tongue weight is approximately 1,000lbs.
