Howdy...it's just a regular Green Gear trailer (the kind used by Bike Friday) that I bolted on to my suitcase. You can sometimes get refurbished ones for about $100 on eBay. It fits into the suitcase fine, but adds an additional layer of finesse when packing. You do notice that you have something on your bike, especially when climbing. The other problem is that you have 2X the chance of getting a flat.

Thailand can be a touch too hot to ride, except in the mountains. So long as you stay clear of the burning season (when the air fills with thick smoke), it's paradise in Mae Hong Son. Also did a bit of riding down south in Chumphoon, which is equally dreamy and has the sea breeze to cool things down.
