I would pay attention to the maximum load (120 kg) (bicycle weight + own weight + basket etc.) and - if at all - use a relatively light bicycle trailer.
Unfortunately, there is no official information on what type of bicycle trailer is recommended. However, most bicycle manufacturers recommend staying under 40 kg when it comes to the weight of a bike trailer. However, I have not found any exact recommendations for this model. :-(
