Oil drum trailer for German tanks

I had designed this small trailer some years ago, I was never happy what came out of the printers. While discussing with a friend I remembered this oil drum trailer.
After less than 1 hour I had a new and much better design. Now I like my small trailer.
The Wehrmacht used these trailers with one or with two oil drums to extend the range of their tanks.
