Sorry for that. There is some science behind how to set up a WD hitch, but not all of what applies is straightforward.
1] How do you know your actual TW? This is with full fresh water, full propane and a normal load aboard the TT. It will be different (likely higher) than the A/S figure.
2] That number, once acquired, is best closely matched
in general.
Andy makes the argument about light bars quire well. And as you have read, there are quite a few who follow that.
The "requirement" is that a pickup have the same Steer Axle weight when towing with WD forces applied as when solo (same day, same truck load) when derived from scale weighings. Three passes across the scale will reveal how much the TT is "removing" from the Steer Axle (Both vehicles, first
with, then second
without the WD applied. Third is truck solo).
The bars can flex up to 4" and move weight around adequately when tested. It may be that 800-lb bars are better than 600, and better than the 1200 recommended.
You will want to know how to weigh your tongue, so see
www.etrailer.com for that tech info on a DIY at-home scale test.
Get that info, and get back to us with the number.
Or, run down to my old favorite truck stop in your burg, Rip Griffins, and do the three scale passes.
IMO, you certainly have the right trailer type, but especially the
right truck.
