. . . I believe what I need is a better gas tank and mount it on the ladder . . .
We've been securing our 2 gal container with velcro straps on our rear ladder for years. As you mentioned previously, with the OEM spout stored inside the container it will eventually leak gas everywhere. We travel with the spout on the outside and secure the end with a pin-hole, vented cap. It's never leaked, expanded or collapsed even in temps as high as 105 deg or temps as low as 0f. Also, we never fill above the "fill" line on the side of the container.
