How many chains/sprockets did you run inside the tube or was it a single strand?

Ours was four sprockets on three axles so it was a slightly smaller version of a 6wd setup which requires putting sprockets side by side which gets trickier for space in the tube.

Here is a picture of a product from Team 221 LLC that shows a double chain inside of 2" x 1" x .125" tubing. Not sure if the sprockets shown are their double 17t sprockets that Rahul linked to earlier.
