you can try mannington trailers they supplied the trailers for awesome I bought one (steel) to replace orginal my orginal one. I'm very happy with mine. They moved the axles a little farther back for better weight distrubution I think but not sure that they offer an aluminum one
call this number here's a nice used platnum trailer that your cat will fit on,it's in illinois but,they are nice guys and easy to barter with,just might have to adjust bunks,ask for mike or cal at xtreme liquidators 217-670-1511
