Pure necessity. Which is a Muther.
We have some folks here at TWT who enjoy making sparks fly and coming up with stuff along the way. Our motto is “Why spend a hundred bucks buying something when you can spend three hundred building it?” They should chisel this on my headstone someday.
The old way… worked OK but left little room and didn't come out so easily. Dozens of holes drilled through the floor.
The next trailer was designed to carry cars and had six hard point tie-downs. Four that were heavy duty D-rings mounted through the floor.
This project had design constraints on both ends and several requirements for versatility scattered along in between. It needed to:
1. Haul motorcycles with reasonable space left for gear
2. Securely transport with a balanced load and common fastening system
3. Use materials and limited skills/tools mostly on hand
4. Provide easily removable chocks for camping comfort
5. Use a low profile frame that could remain in place during trailer camping
6. Use existing hard points with minimal or no further penetrations through the floor
7. Be modular with the entire system removable and all fitting into the back of a pickup truck
8. Enable use of the frame for other hauling tasks that may not involve motorcycle chocks
So, with tape measure in hand and CAD ready to push some lines around… we pondered.
The attachments – create threaded tie-downs to replace the existing D-rings.
3/4" G8 fine thread bolts. If that breaks off we have way bigger problems...
The clean canvas
Pieces...
Chocks...
The KIT...
After some paint... Massey Ferguson grey and Ford tractor grey (what I had)

Maybe it's the unskilled abuse once out of the trailer. 
I tend to think (now) we maybe over-do it some.
