cattle and horses are travelled differently. The sheer numbers allow cattle to brace against each other thus allowing for faster travel ie bends etc. When towing a float, horses can only brace sideways. Drivers must allow for slower stopping, take off and corners.
Also, I see most men with horse trucks or goosenecks.
I tow the camper, horse float and drive the truck. I also drive the truck towing the van, what % do I fit in??

So Horses don't have barriers between them in floats and some padding and along the outside wall as well.
All the ones I've seen do, even the Mounted Boys from South Melbourne behind the Arts Centre.
Even the Thoroughbred Trucks that run around between Ballarat, Flemington, Mornington, Caulfield etc. don't get driven like other people who operate their own floats.
And the Thoroughbred Transport trucks stack 'em in sideways across the truck.
