Actually, Jackie, it's not too new for a
Burro. They were in production with a couple of brief gaps from the early '70s through about 2002.
The
UHaul CT-13 is very similar in design to the Burro 13, but designed for rental use. The frame on the
UHaul is much heavier and uses round tube rather than box steel. It also has a single piece tongue rather than the more common triangle tongue used on most trailers.
UHaul has proprietary wheels, and the taillight lenses are no longer available for it, but other than those minor issues the UHaul is an excellent trailer.
Good luck!
