Crate of beer as cargo I recently bought a two wheel cargo-trailer without suspension, and I am quite happy with it.

My main issue is that it gets incredibly loud when carrying a crate of beer, especially an empty one.

Is there a trick to keep the noise down? I tried to wrap the crate in towels, but it does not really help.

Edit

Cardboard-dividers did not change a lot, compared to my towels. They did look pretty cheap, there might be better ones. 

Tilting the crate 30 degrees in the trailer however, reduced the noise level substantially.
buy cases of beer with the cardboard dividers between the bottles.  You can then re-use the cardboard dividers in other cases of beer.
