I just made my first trip towing my teardrop trailer which weighs around 1000 pounds. The Ascent tows it very well. It's nice to be well below the limit with tow capacity. However, there is quite a bit of rattle when I go over bumps both at speed and going slowly. Has anyone come up with a solution to dampen that rattle? I'm wondering if some sort of shim would work or are there better solutions?
