I don't know what the weight of your tradewind is, but I'm not sure a Class 3 is good enough. I think you need to be in Class 4 or 5. According to the Reese site Class 3 is for 500lb hitch weights and up to 5000lb trailer weight. If you are even close to 5000, I would have gone to the next class (maybe a 5) hitch/mount. Not even sure you can get sway and weight distribution from a Class 3 bar/mount, but don't quote me on that......
