I just bought a lowes 5x8 light weight utility trailer: http://www.lowes.com/pd_100369-1547...RL=?Ns=p_product_qty_sales_dollar|1&facetInfo= I can hardly stand the noise it is making. It is banging beyond belief. I have trailered my buddies trailer many times without a problem. His trailer is probably a little heavier and uses a slightly larger ball. I did try the trailer with 2 large bushes in it to create some weight and still heard the noise. It seems the noise is actually coming from the receiver portion of the hitch. When the trailer is off I can replicated the noise by grabbing the hitch insert and shaking it. I tried to wedge a cedar shingle in but had no luck. Any suggestions? I am almost considering returning it because it makes so much noise. The reviews on the website don't mention noise, just some other cosmetic issues that I can deal with. I am planning on putting in a heavy duty floor which will add some weight.
