I used too have a trailer well it was my dad`s but we converted it so the back slid out then we put a `U` channel for the front wheel too sit in and then put some hook type tie down points in each corner of the trailer and there you have it a multi-purpose trailer. The other option of course instead of using the `U` channel is you could cut out a slot for the wheel to sit into this would probably be a little more stable
Hope this helps
