5th Wheelers in Australia slowly getting accepted

Robert and I have been having a discussion about horse trailers - down under called horse floats. My 43' Jamco is a channel lock alum trailer - easily supporting 24,000 on triple axles. The living quarters section with a 17' slide costs an additional $50k and worth it. Two marine heads, marble countertops, Kahrs wood flooring, induction stovetop, double door fridge, sat tv. Sleeps 6. And, all the amenities of home.
