I liked your comment on keeping warm and I posted a reply.
I liked your creativity on the copper tubing and bamboo poles too.
I found a website that has ALL kinds of trailers and should give you a lot of choices!
My personal choice tends to be the Burley Nomad Cargo trailer even though it costs a bit. It's versatile. I found an excellent short but comprehensive video on this trailer and here is the link:
Also, Graham Williams in London, does a quick review of the Burley. I like to watch his trike travel videos in the UK. He talks about his trikes as well as making free travel videos.
I learned so much from reading and participating on the forum system. Glad to see you contributing too.
