I like the idea that an all aluminum trailer with an aluminum skin would be built. I can't wait to see it.
Also, don't assume that rubber torsion axles are better than leaf springs. Rubber torsion axles don't have an equalizer and the rubber only lasts about 20-25 years before it gets hard. When that happens, it is axle replacement time.
When you hit a large bump with tandem rubber torsion axles, one axle will be carrying the entire weight of the trailer. Also, there are some really good coil spring suspensions out there.
