Bateson deauville storage boxes

[chesnutmare1]

Just wondering if I can get a box of some sort that will fit at the front of my Bateson Deauville trailer! I've seen ifor Williams trailers can have a box that you can move round on wheels but not seen anything for batesons
Just wondering if anyone can suggest anything

Ditto, although there is a saddle rack x 2.

The saddle rack is removable so just want something to go in the space! Think I'm going to struggle.
