About to pull the trigger on this combo. Thoughts?

Looks like a great match. 800 pound bars are not enough IMHO. I suspect TW will be more like 950 pounds. WDH are designed to adjust to support a range of TW, like 600-1000 pounds for 1000 pound rating, or 400-800 for 800 pound rating. I I recommend 1000 pound bars, maybe 1200 if you went with Reese trunion.

I highly recommend a WDH with integrated sway control. Equal-i-zer brand 4-pt, Reese strait line, Blue Ox Prosway are all in the $450-500 range.
