Next thing was that I traded my truck for a half ton because it just was not enough for a travel trailer of that size. Mainly the payload. I was 400 lbs over rear axle rating. The tongue weight of the trailer was about 650 lbs. All of that with perfect weight distribution. Engine power was marginal at best also.
You are correct about the combo. It is a single sway control with WDH. I didn't install it when I was towing the trailer home. Owner didn't use it and forget how it works. I wasn't confident myself.
I noticed a few times when a semi truck passed me, the truck felt like it wanted to sway (a float feeling). I will hook up the sway bar next time. I read somewhere it might be bad to use it for reversing (it might make contact with the bumper, etc).
What kind of truck did you get? You saying with WDH, etc, you were still at 650 lbs in tongue?
