I got to tour one of these at last summer's Oregon Meet at Bandon, Oregon. The owner ( thanks Pete!), graciously opened his Oxygen for tours and questions. They are a very interesting trailer with the feel of a sailboat inside.
I love the look and shape of those trailers. One day if the mister and I ever outgrow the Burro or feel like we want something bigger for longer-term trips, I'll be shopping for an Oxygen.
