Was going to post this in another thread, but it felt too much like dragging out an irrelevent topic.
Here is the setup I'm running with now, only I've sold the waterproof panniers and made some canvas ones instead so I can downsize easier for hitching, and eventually, when I'm in a country with real trains again, freight hopping.
The trailer folds down into a large shopping bag size, and with everything all packed up(takes 10 minutes or less), I can carry all my gear on my back and with my hands, with the bike folded.
This is the living space in unpacks into.
Pretty sure I already posted the bike somewhere on STP, but I've swapped stuff around a lot since. It's a Bike Friday Pocket Llama.
