Buy or hire the Supreme Ultra if...
The Supreme Ultra suits owners looking for a well-established British-built two-horse trailer able to carry a pair of taller horses, since sellers describe it as taking two horses up to about 17.2hh. As a long-running Richardson model it is more often found on the used market now than ordered new.
