I am considering drilling through the walls of my KTM 950 panniers to mount a 1 gallon rotopax on the back of each one. I'm a little hesitant to give up the water carrying capacity of the Gobi's but can't seem to find much info. on anyone actually using them for that. It doesn't sound like a very "user freindly" option, seems easier to just have the rotopax mount on back for gas and water if needed. Thanks for any advice.
