Other than the Bob Ibex does anyone know of other trailers with suspension (homebuilt efforts included)? I'm currently building one - almost finished - but am not entirely happy with the design and was looking for some ideas.

Unless it's done really well I'm starting to feel that adding suspension to a trailer is rather counterproductive; adds weight and weakens the infrastructure. That said, it was quite interesting thinking of all the ways to add suspension to a trailer.

Keep up the good work.
