Thought I had a pic, but couldn't find it.

Anyway, added four more floor tie-downs like the HD ones the trailer came with.
As well as several other lighter duty floor tie-downs and some eye hooks on the fender interiors and on the floor where you won't trip over them.
Invaluble when hauling the shop stuff.

Don't be afraid to bolt stuff to the floor, I lag screwed the lathe - sans carriage and tailstock and off the table - to the floor snce it's difficult to tie down well.

I see a lot of guys hauling this size - and similar - trailers with a standard hitch.
Do yourself a favor and get a load equalizin hitch and sway bar.
Makes a big difference.
