Did the dealer hook it up the first time it broke? If that's the case, they did not do anything wrong.
I am not familiar with Husky Hitch, I heard the name, but never seen one in person.
I tow with a Reese Dual Cam which is also weight distribution with sway control and never had a problem with it and several people on this forum will tell you the same.
A lot of people also use the Equal-i-zer Hitch, which has some similarities to the Husky in how they work, except I have always heard good things about the Equal-i-zer.
I can only think of a few things that could go wrong.
- it may not be installed properly, since I am not familiar with them, I cannot confirm that
- it may be that they are rated for a lighter trailer, I don't know the weight of your trailer or the rating of the hitch
- it may be a bad design which is prone to failure, again I have not seen them.
If you cannot find the cause, I would suggest asking the dealer to swap it for a Reese or Equal-i-zer.
