This is a well thought out unit you've developed. I would think a lot of the weekend gold diggers here in Idaho would look at this as a way to get their extraction equipment to those locations off the motorcycle only NF trails without all that top-heaviness added to uneven switchbacks or a way to pack out all that big game meat in one trip. The mono wheel makes it legal and will fit the single track. Have you experienced any odd harmonics between rear bike axle and trailer wheel suspension on large wash / small whoops at speed?
Papa, would you like your old cell?
