Wow! What great info from all. I sure appreciate all the advice. I think my issue is less about the set up, which I had dialed in almost perfect, and more about the slow change in the levelness of the TV and the trailer.
Crawford Gene: Thanks for taking the time for a very informative response. I too was amazed when hooking up without the WD active. There is no way I could tow without. I have purchased the thin-walled socket for the ball and a 3/4" drive breaker bar along with a 3/4" to 1/2" drive adapter...so no problem with all the monster torques. Instead of adding washers I actually removed one and moved up one position on the L-brackets, with good results. Trailer is perfectly level and the truck is back where it should be. My front wheel well measurement does not change, and the rear is exactly one inch lower when loaded and hitched with the WD. The torsion bars are close to level with just a little bend. I keep the set bolt tight as prescribed in the manual, and check all of the other bolts for tightness. This was my reason for wondering about the WD bars being consistent with placement. It is the only thing that I have not paid attention to.
I did a re-adjust and I am happy with the results. We are heading out for the 4th...but only 15 miles away...so it may take time to see if things hold. Here are pics of my latest (6th or 7th tweak) set up.
