Spaced axle 20 to 24 ft enclosed

I assume you mean spread axle. Most trailer manufacturers are building and pushing spread axles. IMO it's a marketing gimmick and I had one manufacture admit that. Probably was started by one of the many Forest River trailer companies. Once one did they all did it and others followed. I would think that if there was anything to it, Goldrush and T&E would be doing it.
