Trailer

Looking to buy a trailer that will fit a GSA and a GS side by side. Any suggestions?

Motolog are good quality and can be disassembled for easy storage or to fit into the boot of your car. Not cheap though. My single bike version fits in the boot of my astra estate- not sure about the twin version.
Brenderup very good also.

I would avoid the Dave Cooper collapsible trailers-- not particularly good quality, cheapo hubs/ bearing components for example.

Not sure if have Motolog in Germany. Will try find something similar.
"closed" trailer is my other option https://hapert.com/de/anhaenger
