I also have a DrawTite. I called Reese to inquire about adding the sway/cam portions and to obtain new, (reduced load) trunion bars. They said they will fit correctly - but I still have yet to purchase either additional part. I am satisfied with the weight distribution offered by the system. My PO also gave me the set-up guide which I found to be very straight forward. The guide is available on the web also. I finally towed my rig to the CAT scales to tweek my adjustments.
Here's the instructions for adjusting the WD hitch!!!
and another presentation from the drawtite site - which may not be all that accurate/appropriate:
Oh, and there are specifics for adjusting the hitch depending on particular types of shocks, leveling systems with which your tow vehicle is equipped in the first link.
try searching Drawtite - without the hyphen and maybe you'll find some of my posts - which may, or may not, be of any benefit
