I'd recommend the Blue Ox for a Toy Hauler.
I really liked the Dual Cam (which I had previously), except for the above mentioned issue of binding up when you turn too tight (easy to do with the super tight turning radius of my van), and that it can require adjusting the cam seats when tongue weight changes dramatically, like if you had to tow a tay hauler without toys for a trip.
The Blue ox rides a little better too, because of the tapered bars. It does not however, keep things as tight during strong crosswinds, compared to the dual cam. Part of that is the wheelbase ratio of my current trailer. Your trailer will be better from that standpoint.
