You can mount a Koplin 1 1/2 gal fuel tank on the left and right side on the frame. They are out of the way, not taking up bed space, keeps the center of gravity low, protected by the bed sides and still higher than the frame so they aren't hit by anything. With the bed down you have to get back a little to even see them. I've had them on for 1200 miles and only had to use them a couple times on rides over 120 -130 miles, but I'm glad I had them. It's nice to help others out too, when they run out. Thanks for checking this post out.
