I called Blue Ox because I was just very curious what the actual weight is of my hitch head once it's been bolted to the shank they use, and we got to talking. This morning when I'd hitched for the first time, that second sway bar was a real bear to get tensioned. I'd raised tongue jack plenty far enough but that second one was still a rip. Well, the guy told me that it can be MUCH easier to wind on, and also to release that tension if using a breaker bar with a 1-inch socket instead of the provided wrench. Yay!
Second thing, and this has already saved my back. If no one has brought up this gadget, HitchGrip.

It sure helps not to have to be crouched or bent when dealing with a heavy hitch head. There's a little promo video that shows how it works on Amazon's page. Only caution is use the tool in either forward or 180 backward orientation, not at an in between but it's just so much easier.
