I just joined the forum yesterday and I am late also, but those of you thinking about this question might benefit. We have a Blue Ox Sway Pro 1000 and absolutely love it. We pull a 8000 lb trailer (loaded) and it does wonderfully. As mentioned earlier, it is easy to install and the best two things about it is...1. You do NOT have to remove the bars while backing up. 2. There are NO pins with it. With the other setups there is always the chance of losing pins (especially at night) in the process of backing up. As mentioned earlier, the factory sets the torque at 40 lbs. Based on the weight of the trailer, the factory rep suggested I torque my bolts to 55 or 60 lbs. I set it 60 and it is perfect. You are supposed to adjust the torque based on weight. Anyway, it is a great system, very clean and easy to use. I would recommend this set up for anyone using weight distribution hitches.
