I have the trunion bars with my Reese dual cam system. I use max or near max angle on the ball and appropriate number of links under tension to get my front where it should be. With your front measurement a little lower than unhitched, you may be transferring too much weight to the front axle. But I would test tow. With the dual cam system, it seems more picky about having the detents in the bars centered over the cam lobes than a link off on the tension. My TT is rock solid behind a dually at 75mph without WD. Yet I've pulled it a few times with the WDH out of adjustment and been scary at 60mph. But when it's good, I can comfortably tow at 75mph too.
