Yes, yes, you should put this in one/both of the sticky threads. I almost missed this thread because I usually just visit the stickies.

It's a very nice trailer - beautifully proportioned. I'm going to be the Devil's advocate and ask why you think it's more difficult to build than a two wheeled trailer. I've only built two-wheeled trailers, but it seems the Universally agreed upon difficulty is the hitch - the design of which for one-wheeled trailers (like yours, and BOB's ...) is essentially perfected. However the currently popular side-arm design for two-wheeled trailers is less than perfect (in my cringingly humble opinion) - which is why it might seem easier. I think the perfect hitch for a two-wheeled trailer may actually be more difficult to make, and is so few people attempt it.

Certainly the trailer bed has to be more rigid in your case. I'm guessing the trailer weighs about 30lbs.

Could you possibly expand (maybe just bullet points)?

If I make another trailer it may well be one-wheeled, so I'd like to know what I'm getting into.

Many thanks,
