Casper,
I saw several of these at Quartzite , AZ last winter. I'm thinking of one for my 5th wheel. I like that they pivot for off level entries and road dips. And they don't drag the wheels to corner. But I haven't found much on people making them either. I can build my own, but am looking for the best idea for the corner wheels. I have also seen them with one center wheel that looks a lot like the rear wheel on a brush hog. The way I understand it , if they mount up on pivot bolts they become part of the RV as far as tagging requirements go, but they add to the overall length limits of your RV. As far as suspension, it's like my motorcycles on the trailer. The trailer can bounce but the bike's or carts own suspension will take care of itself if you anchor it by the axles or wheels and let the body float.
