Someone else just posted in a different thread here (sorry, forgot who) the idea of mounting a tow ball onto an axle, so when parked, it can be coupled to the extra axle. When sitting on the extra axle, all of the weight would be suported by 4 fullsize tires, and the front axle would be steerable via rotating in the ball hitch. Setup like that, it could then easily be pulled by a single person, or a small lawn tractor. It would require a minor amount of welding, but nothing very complicated at all.
Find a trailer axle, or a cheap trailer you can rob the axel out of. Weld some box steel on the top of the axle in the center, to match the amount of rise you need to make the trailer sit level. Drill a hole in the top of the box steel to mount a ball to. Weld two small plates of steel to the front of the axle, with a hole drilled in them that matches, so a bolt can be slid through. Make a tongue for it out of another piece of box tubing, with a hole drilled through one end so that it can be bolted onto the front of the axle, and pivot up and down, then make the other end of hte tounge a handle (if you plan on pulling it manually ) or two plates with hte hole in them to pin it to the back of a lawn tractor. This way, when the secod axle is coupled to the trailer, all of the weight is suported, and you only need to lift the weight of the tounge of the second axle, and then pull it.
