There is a photo of it in Trip planning," got gas". #33 I leave it on most of the time. I only have to fill it up every 360 to 400 miles (plumbed into the main tank). I have almost 75K with this setup. I usally throw my camping gear on top, but I it set up that I can strap things on the sides on top of the bags. It's been great running the back roads out west where the little local gas stations want an arm and a leg for gas! I just smile, and keep on rolling.
