Go to the towing forum and read the first sticky that discusses setup for the dual cam WDH.
Nothing terribly difficult in getting the right amount of weight transferred back onto the steer axle on these hitches. For an F250 older than 2011, you should be aiming to get the front fender height back close to the unhitched height (no trailer on the hitch ball). You want 5 links under tension and maybe 6 with trunnion bars. Not sure for round bars. The bars will point down at a slight angle if trunnion bars and close to level for round bars. If you aren't getting back close enough to the unhitched front fender height, you need to tilt the bars downwards more by adjusting the large square serrated washers. You definitely will need to raise the rear of the truck to get the chains in place on the snap-up brackets.
I couldn't find the right GVWR for the TT as a couple of sites had different numbers. I'm guessing that the tongue weight is going to be around 700-800 lbs meaning that 800 lb rated spring bars are what you want. If the tongue weight is much above 800 lbs, you may need to go to Reese's 1200 lb bars. It would help to know your actual tongue weight.
