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.
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.
