Advice on strapping down a load.

[REV73]

Hey guys. I have taken the sides off of my box trailer while it is out to paint, and really like the look of it as a flatbed. I am considering using the trailer like this for a while to haul around 2 of my 1/16 International tractors. However I don't really know how to go about this. The bungee cords I found are small, but not small enough to look realistic, plus the length is not right, so I was wondering what some of you are doing to strap down stuff to the trailer. Any advice you could offer would be good and if you are able to maybe add a pic or 2 that would be awesome. thanks everyone.
